My apologies for the delayed response to this thread.
Can anyone please confirm if this issue is still occurring in the latest v2.0.1 version of Connect Mobile for iOS? We have been unable to recreate this issue on our end?
The Average and Maximum cadence figures quoted on the graph look OK for me since version 2.01 (i.e. they match those shown on the GC website and tally with figures actually plotted on the graph within the App. The wonky 'Average' line I reported in this thread for the Pace graph still happens though. I provided screenshots in a separate thread - https://forums.garmin.com/showthread.php?76818-Spurious-(Average-)-Line-Shown-on-Pace-Graphs
