As I get used to the Nexus I'm using manager a lot but I'm getting a lot of disconnects and having to press "-/+" to get back to using manager ... takes me back to the main ST page and I have to press edit to get back to where I was in the settings.
I'm using android 8.1.0 on a Samsung Galaxy tab a6 ... no problems apart from disconnects.
This was happening from 1st setup using Nexus launch firmware ... I installed the controller firmware 20220210 yesterday but the same problem persists.
Also there is no pattern of time between disconnects, it's random and can be just 2 minutes, but usually about 5 minutes or more.
