I have Fenix 5, Edge 520+, Iphone 7. All with the latest software.
I turned on the Physio Trueup but Garmin Connect ignores all data from Edge.
I waited for a month believing that it just needs more data :/
It does not need any more data, it is just poor software, as it always was.
I had Wahoo Bolt and I traded it just to have Physio Trueup.
I wasted money and time on that option.
