Watch keeps freezing during activity. Anyone else?

I've had the watch for 3 days. I've done 3 activities.

6.5 mile road run. Worked great.
7.5 mile trail run. Watch froze on the evelation screen . Had to hold power to force shutdown. Then power back up.
27.3 mile trail run. Watch from THREE TIMES all on the elevation screen. While running I decided to delete that data screen, promptly froze again immediately after. Loop course, the loops it worked the watch was great.

I have trail run settings on GPS/glonass. Every second. OHR on. Auto climb on.



Any one else having this issue? I'm considering a mass reset.
How do I do one?


Thanks.

And for reference. With those settingsy battery went from 97%-68% in just under 5 hours
