Hi,
There's an issue on Fenix 7 where vibrations stops working after charging and removing the cable from the watch. This stops working after the shutdown / reboot. Happens everytime for me on Forerunner 965.
I was asked to report it here as well because it's different engineering team...
Please let me know if you need more info, it's really annoying bug which needs to be fixed ASAP.
I'm on 17.26 version.
