Network settings
I have a problem with app's cellular settings (on/ off states are fixed, no way to change whether app can or cannot use a mobile network) and I cannot setup any VPN profile (both issues reported). The former strated with iOS 12 or 13, the latter with the latest 14.6 public beta 2.
Now I have tried to Reset All Settings and Reset Network Settings. According to the Apple Support website after that all my Cellular, WiFi, Bluetooth and VPN settings should be cleared and I can start from scratch. Well, the only *visible* change in the "network area" is a loss of WIFI passwords. Bluetooth settings are still there (I have no problem with BT sett., but I expected to have them cleared), cellular are stucked as they was, VPNs cannot be created (I have no VPN profile and have "Error Domain=NEVPNErrorDomain Code=5 total NetworkExtension configuration size limit exceeded" it's from Wireguard log).
Is there a way to REALLY clear the settings (via iTunes, DFU or anything else) without erasing user's data?
Backup-EraseAll-Restore procedure via iCloud and iTunes did not help too.
