For the last one week the Heart Rate Zones graph shows that the whole activity was in Z5 but it is not correct. When I hover the mouse over the zones for the recent workouts it does not display the zone limits but when I do the same in a previous workout I can see the limits and the graph is working fine.
I have checked the zone settings several times on Garmin connect, Garmin connect mobile and Fenix 5 and they are the same. I have changed the values several times and confirmed that they are syncing correctly between the watch and the Garmin connect.
There is a similar post from 2016 but the solution there is to make sure that the heart rate zones on Garmin connect and the watch are the same, but I already checked that and it did not solve the problem.
Any ideas that I should try? ciq.forums.garmin.com/.../1253818.jpg ciq.forums.garmin.com/.../1253819.jpg ciq.forums.garmin.com/.../1253820.jpg
