A few points:
- The device is running Android 10, so a recent version
- A similar app built by us (but significantly smaller in size) loads fine
- trying to manually install the app via self service in SM shows 'downloading' toast , then nothing
- I have tried debugging via USB, but nothing useful in the log.
The _only_ thing that works is loading over USB via ABD, then Meraki seems to pick it up, but this is not ideal.
