Software 21 uploaded to the watch through Garmin Express via USB cable. Watch did not tell me it had an update ready to install until after I disconnected it from USB. That may be relevant? Anyway I pressed yes update on the watch, it did its thing, and ended up on green triangle of death. None of the buttons did anything. Had to force power off and back on. Now it says it is software 21 in settings about, but I can see quite a few things missing from my data. Records, latest activity, and so on, no longer there.

Watch seems to work otherwise.

Is this going to be a problem? I'm suspecting that the software update did not correctly complete all the steps it needed. I tried synching again but it just says up to date.
