Since the Field Maps iOS update on 3/28/2022, it appears an old bug has made its way back for our users with tpk basemaps.
We run custom NAIP tile packages and now when a user zooms in past the tiling level, the basemap goes white. This issue was fixed awhile ago as I can zoom in past the tiling level no problem in Field Maps 21.4.0, but when I updated to 22.1.0, the issue is back on iPhones and iPads.
I have told our users to hold off on updating if possible, but many have auto-updates installed. Can this be fixed again in a future version of Field Maps?
There is a work around that was posted for iOS users on another thread and it has worked for me as well!
