I have a Field Maps app utilizing the Indoors model for site floor plans. When I zoom to some of my sites in Field Maps, I can see my units layer for a second, and then it disappears. Even when I choose a different floor from the floor picker, I still can't see the floor plans. I've tried toggling the units layer on and off, and it doesn't help. This seems to be happening more often with larger sites with many more units. Smaller sites show up and don't disappear.
