I am experiencing the following problem with my FR945 on iOS. This morning I woke up and went for a run with my watch and had my HR recorded - it shows up for the entire duration in the run details.
However I noticed that on the HR timeline in Garmin connect (both on iOS & web) the heart rate details are missing for the time I was running - attached is a screenshot.
The FR is running software 4.40. This has hapenned to me once during the last week as well - I was not doing a workout but had random HR data missing for a period of 2 hous even though I was wearing my watch.
I also noticed that the steps are missing from the detailed overview. Even though I see a total steps of 17,600 I do not see the exact steps split per hour of the day.
Does anyone have an idea what the problem might be?
