Apple Watch 3/Watchos 5 - Swimming not counting laps or calories correctly.

I have an Apple Watch 3, and just updated to WatchOS 5 yesterday. Today during my swim workout, the yardage counting is completely off - I swam 6500 yards, and it shows 100 yards. The calories burned are about 4-500 different than normal, the auto sets are completely wrong/missing as well as times and everything. Is there a bug with the new watchOS and swimming? Anyone else have this issue? I swim the exact same distance/time 5 days a week and the Apple Watch workout app has always been extremely consistent in measuring distance, time, strokes, etc. I count my laps and the Apple Watch historically always got it exactly right. Now today, after watchos 5 update, it's not even close.

Thanks,

Andy

I called Apple support and they helped me solve the problem. It turns out that force quitting the app, powering off and restarting the watch and then unpairing and re-pairing the watch fixed it. It counted correctly yesterday.


In reality, I think the in pairing and re-pairing is what worked but I listed everything they had me do just in case it was some arcane detail in the sequence.
