Hello, my Deco P9 app used to control all connected devices properly and recentlly stopped doing so without any visible reason. Tried the app on several devices - iPhones and iPad - app detects the connected devices but cannot block any of them in the Parenteral Controls section, indicating 0 mins online time (reports are missing), also showing some of them as offline while being in use.
 

Multiple restarts/reboots were done, everything is updated, app deleted and downloaded again on an iPad without any success to block any of the connected devices, while all of them use one and the same network. 

Can you help with any suggestions?

Thanks.
