Crash and Reboot when enabling Navigation during Run, health data missing (F7Pro, 21.19)

Today I had a crash again: in the middle of the run I ensbled Navigation: Back To Start (Route). Still within the first seconds the watch crashed and rebooted. Seems it does not like too much calculation.

Not only part of my run is missing now, even the whole day with stress and body battery is lost: it's still shown on the watch, but never syncd to Garmin Connect.

What can I do to avoid these crashes?

  • I'm afraid you can't do anything.
    Those crashes are in place since a year probably...
    The team that is working on the old devices is absolutely not capable of fixing the issue.

  • The amount of crashes/reboots on this release is getting ridiculous!

  • The crash is a bummer, of course.

    But I find it much worse that the sync of data stored on the watch to Connect can't be repeated if there was an error. It's incredibly amateurish to apparently tag this section as synchronized, even though the sync never actually took place successfully. We're talking about errors by Garmin that affect all the scores. The days with the highest stress levels in Connect are the days when sleep suddenly disappears. You can imagine the training readiness shown...
