Garmin Swim 2 sometimes crashes during pool swim workout.

This is super annoying! This happens during workouts I have entered myself via the Garmin connect app. I get either a white triangle on a black screen or the watch face, after hitting the lap button or reaching the end of the length. Is this happpening to anyone else? What is the solution other than returning the watch. Because quite frankly it defies the purpose of the watch if you are standing at the shallow end flicking through half the workout you have already done, but hasn’t been recorded, just to carry on where you have left off.
