Since a couple of months, my Deco iOS app doesn't show any online devices/clients, which used to work just fine before.

I've got 3 X50 Deco modules. Everything seems to be working just fine and devices do connect to the Wifi networks. But they don't show anymore on the app.

Restarting the modules sometimes solves the problem for a short periode (30-60 minutes perhaps). Later on, no devices are showing again.

Re-installing the Deco app solved the problem a couple of days last week, but the problem has arisen again.

- firmware of X50 modules is up to date (1.4.5 Build 20240828 Rel. 84587)

- iOS (v18.1.1)  is up to date

- Deco app is up to date (v3.8.129)

What is wrong?
The app has worked fine for over a year, but now doesn't any more.

I see this problem posted several times on the forum last couple of years. But I can't find a cause or structural solution.

Please help!
