A few days ago I turned off tones and vibration alerts (under Settings > System > Sounds > alert tones and vibrations) as I wanted to run a race "naked" while still recording the distance to look at later. I have since turned these back on, but while I haven't changed anything else, alerts have disappeared for things like successful Bluetooth connection.
I haven't amended any other settings, just those two, and turned them back on immediately but those other alerts aren't happening.
Any idea what is going on here, or how to fix it?
Thanks
