I have made the following observation: when I record a cycling activity with my Edge 1040 solar, I receive a recovery time afterwards as normal. After synchronisation with Garmin Connect and thus the FR 965, I always receive the message "Delayed due to high activity" after 1-2 hours in the recovery time. The recovery time then stagnates for a while and reduces very slowly. However, when I record a comparable cycling activity with the FR 965, I never get this message.
The FR 965 is set up as the primary device. Before that I had the 955 and before that the 945lte and 945. I did not observe this phenomenon before.
Has anyone made a similar observation?
