After the last update, the pool swim activity has been struggling with accuracy. The two swims I did last week both had issues after doing drills where the 100s were only measured at 50 and 75 - but the time was measured the entire time. This morning when I swam, the entire first 300 and then next 50 were not captured at all.
I have not had this happen in the past. It’s been pretty accurate with tracking prior to the update. And no - my technique and flip turns haven’t changed.
