Here in 2022 and now have a nonfunctioning Galaxy Watch Active 2 after swimming. I set water lock mode before, but now the watch does not seem to do anything.  I thought the watch active 2 was waterproof.  I have now checked several message boards here and Reddit and see many others with dead watches after swimming. Is this official? The Galaxy Watch Active 2 is not waterproof even after water lock mode is enabled.
