I also have a FR55 and I can see the heart rate in Strava. I can see the graph and also the min- and max heartrate. As a free user, I just cannot see the AI analysis of the heart rate, the rest of it is there.
hmm that's strange.. I have a paid strava subscription but i still don't see it.. only once recorded an activity.. but otherwise no hr available.. what settings do you use?
I do not use any special settings, mostly just on default. My FR55 does have a watchface installed, cannot remember the name now but it's one with larger letters/digits so that i can see them better, I am 62 years old.
