Charge 3 not autorecognise exercise

[KnackeredPigeon]

My charge 3 has decided to stop tracking my daily swims again. 

I swim continuously for 25-30min, with a short (3-4 second) pause at the end of a length to catch a breath. Autotracking is on etc, and I'm just doing standard breaststroke or front crawl with no floats or pull buoys.

I've tried

- changing the clock face

- soft reboot

- factory reset

- uninstall everything, reinstall and pair

- change the autotracking period to 14 minutes, then save it, then change it back to 10 mins

- stop all apps and then go back into fitbit

Nothing, nadda, zilch, zero. Has anyone got any suggestions (apart from my next option, which is buy a garmin!) that might start it tracking swims again

Thanks in advance
