Ace 3 losing time

[LongtimeWearer]

Lately my daughters Ace 3 won’t keep time. It’s behind about 45 minutes. It will catch up with we sync it but it continues to  lose time. Any ideas on how to fix this?

here are the support contacts I've gleaned over the years on the forums.

when there is someone available, chat is an option. Phone or X/Twitter works well, too.
