"Unable to connect to Deco" - why does this happen?

As the subject says, "Unable to connect to Deco" on the Deco app, Wifi is working as normal with the Deco light still green, however I need to reboot the network in order to restore control from the Deco app.
My network of the X60 as main Deco in router mode and a Deco XE75 Pro as satelite Deco, is stable, fast and I'm very happy with how the Decos work, however I can't seem to get past 2 weeks running the network without getting the "unable to connect to Deco" on the App?
I find this most frustrating. Coming from TP link Archer routers that I used for years that could run for over a month with no issues, how is it that Deco can't even make 2 weeks without an issue?
Thanks
Kevin

Can I have the current Deco APP version?
Does it make any difference if you delete the Deco APP and log into the previous account again?
(Deleting the Deco APP would not mess up with the current network configuration.)
By the way, Did the Deco APP also report "Unable to connect to Deco" when the mobile phone is connected to the 4/5G mobile data?
Please also refer to this link to help me submit the Deco APP log:
Wait for your reply and best regards.

Hi David, thanks for your reply.
I've submitted the App log as requested.
App version is 3.9.9 and up to date.
I've deleted the Deco app now and reinstalled it, or do you mean to do this when I have the unexpected behavior?
On 4G/5G the behavior is the same and makes no difference.
Regards
Kevin

Hi, Thanks for the APP logs. It has been forwarded to the engineer for further analysis.
It is very likely the communication between Deco APP and the Cloud server was interrupted. Have you ever configured any DNS filtering or Access Control rules for the local network?
Please also check the email for more suggestions.
Best regards.

Hi David. Thank you and I've also replied to your email. I've never touched any DNS or access control rules for my local network.
thanks

I swapped my Decos around so my main Deco is now the XE75 Pro, I remember now why I've always had the X60 as main Deco. I've listed below an issue I had last year when I got the XE75 Pro but never made a post at the time as the X60 seemed to perform ok as main Deco.
Issue: With the XE75 Pro as main and X60 satelite on wireless backhaul, any device connected the satelite X60 is not seen in the online clients list altogether.
On wired backhaul any wifi device connected to the satelite X60 shows as a wired connected device and under the network "map" it shows no devices connected to the satelite Deco. Some screen shots below.
X60 satelite is connected directly to main XE75 Pro via ethernet cable, there is a switch but it is connected directly into the X60 satelite into the second ethernet port.
Any ideas? Can these issues be fixed or as XE75 Pro is end of life maybe it will never happen? I'm looking to go back to TP Link archer routers with easymesh as at least they work properly and when I was using them (2x C80's) I never had any issues, the above all be them small issues with the Deco its time consuming to come on here and report them etc etc....
I've switched off fast roaming and it made no difference.
Thanks
Kevin
1st screen snip - X60 shows no devices connected. However I know my iPad, iPhone and Firestick are connected to the satelite X60.
2nd screen snip - under network map I see this, devices connected via wifi to X60 are showing as wired all the time. Home CCTV is correct as a wired device into the main XE75 Pro Deco.

Hi, Thanks for the update.
I think it can be fixed as Deco XE75 Pro is still a hero model for the Deco WiFi 6E series.
I believe the current situation may be mostly attributed to the Deco APP but I want to see what the engineers think of it.
Best regards.

Any updates on what the engineers said please RE: the X75 Pro showing devices as wired or not showing at all on the Deco app? BTW I've changed my network back to my X60 as main DECO.

Hi, Nice to see you again.
I checked the previous ticket record, and it seemed the engineer didn't find anything useful in the APP logs.
I noticed the previous Deco APP was 3.9.9, so if you were still on this version, it is suggested to update to 3.9.12 in the APP store as there was some abnormal feedback about this version:Deco App and Internet disconnection
Wait for your reply. Best regards.

Thank you, sorry think there is some confusion as this thread actually covers 2 issues now:
1) Unable to connet to Deco issue on App (my original post) - I'm aware the engineer could not find anything at the time in the Deco app log and I told him to close the ticket and I would see how I get on. BTW I'm always on the most up to date App version as my iPhone updates as new versions become available.
2) See thread #5 of this chain where I set my XE75Pro to main Deco and X60 to Sattelite Deco and then reported abnormal behaviour in Deco app, this is where you said you would see what engineers think (thread #6), what did they say?
Thanks

Hi, thanks for the update.
He only mentioned there weren't any relevant details in the submitted APP logs, and there happens to be a new Deco APP ready for release that has fixed several reported bugs. So he thought it might be worth a try.
However, if you were still having previous issues on the latest 3.9.12 IOS APP and would like to spend a little more time with us, I think he would be glad to help:
- No devices connected to the satellite Deco X60
- Devices connected via wifi to X60 are showing as wired all the time
(Please still help me submit the latest Deco APP log)
Thank you in advance and best regards.
