I upgraded from 39 to 40 and I think the only issues I had were:
- Background I was using got removed, got a better one anyway
- A few gnome extensions stopped working and I had to update them or find an alternative
- Had to re-create virtual disk mapped to real disk for booting windows installation in virtual box (there is a sonicwall VPN I have to use for work which only works on Windows)
I think that was it!
I have had some strange behaviour from Firefox saying it’s become unresponsive a few times and at the same time Thunderbird but that seems to have fixed itself now
I use phonetrack, works very well and haven’t noticed any battery drain from it at all or it cutting out or anything like that. You can also configure how often it updates GPS/location on the server, can detect type of movement to increase/decrease polling and things like that. On the Nextcloud side I can share a map with my location and it updates a lot faster than Google does. Doesn’t look as polished but it works well.
