If you're not able to log in to Zenoti Mobile (ZMA), see blank screens, or if your screen is buffering, try these troubleshooting tips:
Uninstall the app, then reinstall it. Try logging in again. It should work.
Note: You may not have the latest version of the app installed - this trick normally works.
Reach out to your owner/manager to check your geofence settings - you may not have the permissions to log into ZMA outside of geofence.
