Has anyone else seen an problem when completing a pool swim that the watch isn't displaying distance or lengths? It's happening intermittently for the last couple of years and it's fixed by a restart of the watch (I've not yet tried just closing and reopening the app). I'll swim a couple of lengths, see the watch hasn't updated the display except for the timer and possibly the calorie count. If I stop the workout and go to the summary screen, the lengths and distance swam is then shown correctly. I've noticed this on a couple of series 2 and possibly a series 3 watch.
