I just got my forerunner 255 today and it was all working well and I even recorded a couple of activities. Then, there was an auto update to 11.12 software version and now I don't see heart rate or any other sensors working (barometer, altimeter, compass).
Now ideally I would've rebooted and done the troubleshooting myself, but after having read the forum, there seems to be a lot of issues with the watch getting bricked?
I just got the watch today and this is super frustrating.
I trusted garmin inspite of having a Forerunner 245 earlier which had the white pixel/dot issue.
I live in India and I don't know if service center is the right approach as based on my past experience, they're extremely slow to process.
