This fix didn't work for me. Any thoughts? QuickPanel Restore installed fine, said it updated, then uninstalled. No mobile data toggle, so I restarted. Still no availability of Mobile Data quick-toggle. Re-installed QuickPanel Restore... now pushing the button says "already updated". These are the only quick-toggle options I have:
WiFi
Bluetooth
Mute
Screen Rotation
Flashlight
Wi-Fi Calling
Location
Powersaving
Airplane Mode
Do not disturb
U. power saving
Smart stay
Screen Mirroring
NFC
Sync
Private Mode
This is a huge PITA as I have to turn mobile data off frequently while at work, or lose 10% of my battery every 30min. :-\
