Personally, I train for multisport every day, but indoors. The activities I select are as follows: treadmill, indoor bike (smart trainer), and pool swim.
The problem is that when the activity ends, and I check the record, it seems to be missing the graph section. It only shows the summary, where you can see how you performed from the beginning to the end. The graph is only available for the pool swim and is missing from the indoor bike and treadmill activities. If I start the activities individually, everything seems to work fine. What could be the issue?
However, if select multisport activity which is treadmill, indoor bike and indoor walk, this multisport activity will have the graph option at Garmin connect.
Also, with the same multisport configuration, when I start the pool swim, the entire watch crashes and reboots. This has happened three times already. There was even an instance where, after the watch rebooted, it crashed again when I tried to resume. It only worked fine after the fourth reboot, which is terrible and wastes time.
