Up to the latest release, my watch was spot on. Never had an issue. Ive been swimming every day for 10 years. Same stroke, same pace.

This release does not get the number on lengths right. My pace is about 40 sec per 25 m breast stroke. It is like clockwork. Now I get 40, 40,40,1:10,40,1:20, etc.

And I get odd length counts say 39 laps when I did 44.

How owe can I roll back versions? As this Vers is useless for me. It has been wrong every since swim. But was not before :(
