I recently (had to) upgraded to a newer tablet because the old one was no longer going to work with T-Mobile. So, I moved my Lightroom mobile over to it and get a message that 'Syncing over cellular network is currently disabled. Tap here to change the settings.' So, I tap here and am taken to the preference menu. There is no sync options here. I have deleted and reinstalled the app, still, no joy.
While I sync over WiFi when available, when I am away from WiFi, I still need to be able to sync over cellular to edit, show clients, etc.
Other posts refer to a Cloud Storage and Sync option, but that is not there. Syncing over WiFi seems to work fine.
