Thanks for sharing! Most of our field users don't have Trimble configurations set, however they all do have the Trimble Mobile Manager app installed. We will keep an eye out for users using GNSS devices and I will update the post if we see the same.
The good news (so far) is that removing all previously downloaded maps and redownloading seems to fix the issue. We are thinking there may be something in the new version of Field Maps that previously downloaded maps are incompatible with.
