I've got a suggestion from TP-Link Technician in Thailand to change DNS setting to 8.8.8.8

Since 4/4/2024 8pm until 6/4/2024 10AM, so far only 1 CCTV disconnect

I will update the final again soon

Still offline very often

So far it still happen but I figure it out that because one iPhone entering the IMOU App and then the Deco collapsed.
Once the iPhone leaves the App, the Camera comes back online.

Just only my wife phone (13 Pro Max), her phone memory is almost full 512 GB. I don't know is that the cause or not?
I have tried to invite other iPhone into my IMOU App but nothing fail.
