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.

iPhone 8 Plus, iOS 14

Well, I used paid, 3rd party app (I will not name it directly, I believe I'm not allowed to do it), one of the "iTunes alternatives" that allows editing backups, and it did an amazing job. I decoded and checked system files and I decided to delete "DataUsage.sqlite" and "CellularUsage.db" at "WirelessDomain\Library\Databases" for my problems with cellular settings. For my VPN problems I removed "SystemPreferencesDomain\SystemConfiguration\preferences.plist" and "SystemPreferencesDomain\com.apple.networkextension.plist".

After the restore, I have now 100% fully working iPhone, finally.

I wonder why "Reset Network Settings" does not clear these files? And "Reset All Settings" as well?

I finally managed to solve it by doing a local backup, removing five files from it (they should be cleared by Reset All Settings but they are not touched by the procedure, which I find very strange) and restoring the backup.

Now my Cellular data and VPNs are working as they should work after Reset Network Settings.

Apple, clear more files during the reset procedure. Seriously.

This is not the right forum to discuss beta

When you experience an issue or something does not work as expected in beta, send your feedback directly to Apple with Feedback Assistant.

You may have Screen Time Restrictions set to ON.

Open Settings ➔ Screen Time ➔ Content & Privacy Restrictions ➔ Cellular Data Changes : Set this to ALLOW.

So let's discuss the 14.5 because I updated to the beta because I had problems with "Reset Network Settings" in 14.0, 14.4 and 14.5 ( I try it after every upgrade) and then I tried beta 14.6.

I personally have seen the same issue (cannot create a VPN profile) with the same error: "total NetworkExtension configuration size limit exceeded" on 14.5.1, 14.6 and now 14.7

Glad you managed to solve the issue. Can you share the names of the files in question? How did you edit the local backup to remove the files?

Thank you for the details. You are my hero as this has been blocking me from installing a vpn profile I need for work access. I know what I will be doing this weekend. Thank you again.
