2. change the DNS server to be 8.8.8.8/8.8.4.4, such as

If the issue continues, please try to turn off the Wi-Fi and enable it again to check whether it starts again;

''Also disabled mesh for my iPhone but it seems to be ignored... I read somewhere that this a known issue. '', Did you mean you could not disable Mesh on the iPhone 12 pro?

and for the ''somewhere about the known issue'' can I have some links, please?

Currently, except for the iPhone 12 pro, what are the other devices that have the same issue?

Thank you very much.

@Avri 

Thank you and  I would like to follow up on your case by email for further assistance.

By the way, except for the IOS devices, did other devices work fine with these applications, like android or windows devices?

Since previously you mentioned that the issue only existed on the main Deco, If connecting to the 2^nd Deco, these application works fine; would you please check it again on the connection with the secondary deco?

@Avri 

Thank you very much and the case has been forwarded to the senior engineers for further assistance.

Please check for the update on the email.
