pool swim activity is crashing since 26.08 randomly

Since upgrade to stable 26.08 firmware, when I use pool swim profile watch reboots and kill activity randomly after resume. (after some time)

More often during auto pause. Watch reboots and do not continue activity.

Mainly | use this profile to track time on a pool, now I had it at last 4 times.

looks like FR955 have the same issiue:

Please connect your watch via charging cable to a computer and sync with Garmin Express. This will put the watch through a soft reset and should resolve the crashing.

Same for me, the garmin express truck didn’t work.
Here is what I do before crashing:

- start swim with 33.3m pool

- 600m free swim

- start drill mode

- drill mode for 12min

- stop drill mode : CRASH

The same for me.

Crash in drill mode or not but after 1800 m.

Garmin support told me to reset completly the watch. It solved the problem during one week or so (I swim everyday). Now, the crash is back as previously described.

Garmin, thank you for solving this asap!
