I have a FR970 and I use it to go to swim often.
What I noticed since I have it is that quite often during my sessions the watch skips a set randomly.
More precisely this is what happens. I am doing a structured workout and I press the lap button (I have auto-rest off). After the rest is over, the new lap series starts, but instead of starting it starts in "rest" and it counts the series as done. This messes up pretty much all the statistics as you can imagine.
You can see in the image attached what has happened just before the 220 freestyle series.
First it was a 240mt series (and I've done 240mt) but when I started swimming for this series - immediately when the rest timer went to zero - the watch did something weird, it started in rest. I didn't even realize, then when I was half the first 20mt the watch turned again into the main exercise (as if I clicked the lap button). And it did all of this automatically without me doing any interaction with the watch.
I am not sure if this is a software bug, some problem with the lap button contact or else but definitely not great. Does anyone have the same issue by any chance? Is this something wrong with my settings, my watch or it's a sw issue?
Thanks
