Might be pure coincidence but did my first interval run with the 14.13 fw and during the latest interval it went into some auto-stop loop after manually pausing to wait for a stoplight.
After I pressed resume it immediately stopped again, pressed resume again, it stopped again (within 1 or 2 seconds). Then thought 'screw it' and chose to save the activity after which it hung at the 'saving acitivity progress circle'.
Watch didn't seem to respond and then suddenly got the message that the next 'interval' started (the 'cooldown') and I was in the activitiy again which was running. So I finished another km or 2 and saved it, which then worked fine and it synced fine.
Anyone ever experieced something similar?
I think I remember once where the watch acted strange when I manually paused a run at the EXACT moment an (auto-)lap ended though I don't recall exactly what happened so perhaps it's just a rare coincidence. But as it's the first run with the 14.13 fw, well...
Doing a normal easy run tomorrow and some more intervals next week so we'll see how that goes.
