Welcome back -watch restarts when using tracback

First of all a warm welcome back to the garmin forums!

I received my watch a week ago during the outage. I connected it to the garmin express application and updated to 9.20 stable version.

I like the watch a lot, especially the crisp display, and hr reliability also seems very good for an optical. During a short walk, I tried to test a feature that was a great part of what got me to buy it, the tracback navigation. I was dissapointed. Watch restarted at least 3 times making the feature nearly useless. I attempted a master reset and tested again in my backyard but the watch keeps restarting again. Is something wrong with my watch, or something I have to live with?
