I use Resume Later from time to time. I tried it today for the first time on a Fenix 7 on 15.74 and although it returned to the watch face ok, I could not resume it. The start/stop button was not responsive so I could not get to the activities list. I eventually restarted the watch, but it hung on the copyright screen and on the second attempt on checking maps. I eventually had to do a restore results. The paused activity has gone. (At least I found that the restore backup works.)
A new bug or just a one off? I'm not very keen on trying it again?
