I want to follow up on this. Our base maps via Field Maps use to zoom PAST the cached layers defined scales up until a few weeks ago. I'm thinking some sort of update changed something. I opened up the exact same map in Collector and we can still zoom in past the extent of defined scales. This is new to Field Maps!
How do I get this back? If this setting was removed from Field Maps then I think it needs to come back. We are using a GPS with field maps and sometimes we need to zoom far in to see points that they GPS that are within 5 feet of each other. Having the aerial basemap disappear on them is making it difficult for them to do their job.
