We have a new beta rolling out with the fixes that @seadowg mentioned! Hopefully those work for you @ahblake
Not related to maps, this beta adds periodic auto-send retries at an increasing time interval after an auto-send failure. To support this, we had to make a change to how WiFi vs. cellular is detected. If you use "WiFi only" or "cellular only" auto send options, I recommend testing this out. I've updated the first post in this thread to reflect this.
An additional change is that we've renamed "reference layer" to "offline layer" as discussed in the design thread.
The beta also adds the possibility to delete mbtiles files from Collect's storage:
Note that the icon for that delete button is currently a + when it should be a 
. We'll get that fixed shortly but it should not affect behavior.
Do these all get used from the same device? When does the user switch between them? Could the data be represented as geojson or entities with geometry if we had a way to display that kind of data as context when capturing a point/trace/shape? Same question for you @ahblake
Unfortunately not as far as we can tell. Some options you have:
- Use Google Drive to distribute the files. The file picker should allow access to those and they will be downloaded directly to Collect. Some things you've mentioned before make me think you may not have Google accounts on your devices so that may not be a good option. Note that you could share a single account across devices (mycoolmbtiles@gmail.com)
- Manually delete from downloads after the files are confirmed to be in Collect
- Delete from Collect using the new functionality mentioned above after a certain layer is no longer useful
