I can't wrap my head around this, but seeing people having problems with 14.13, 14.17 and others firmwares below that ( if there were any) seems that Garmin makes more bugs than they fix. I literally bought 955 in January and just updated one firmware and then disabled automatic updates and thank god for that. I know I have LTHR bug ( where it updated only two times in one month while running pretty much 5 days a week), BUT thank god I don't have "Navigating to saved route", translation errors, music errors or any kind of touch problems. Everything seems just work for me, I have battery drain of 0,450 to 0,500%/hr while having a either bike/swim/run actviity every day, have every-second measurement turned on. HR sensor pairs, Cadence sensor pairs, distance/pace measurement seems okay.
I sold my Coros Pace 2 and went to Forerunner 955 to have a way better experience, which I have in a way, but I didn't think that I have to disable automatic updates just to don't get more bugs.
Sad :)
