Since updating from 13.5.1 to 14.0 Public Beta 2 on my iPhone 11, I'm unable to turn on mobile data for specific apps. When wanting to change mobile data usage restrictions for apps, the system would not register the change of allowing mobile data. Description: Using Settings > Mobile Data, I find the specific app and select "WLAN & Mobile Data" from the 3 options. As soon as I leave this page to launch the app, I continue to receive a prompt asking me to allow mobile data in settings - eg the app is still disconnected. On the settings page, I find my selection of "WLAN & Mobile Data" reverted back to "WLAN" - usually as soon as I leave settings. Impact: This bug makes my iPhone a useless paperweight when it's not connected to WLAN. All apps that didn't have mobile data access prior to the update are affected. Common solutions I've tried (which didn't work): iPhone Restart / Force Restart Play around settings for mobile data - toggle roaming Reinsert sim / use a different sim. Delete and reinstall affected apps Disable Content & Privacy Restrictions in Settings > Screen Time Reset network settings Reference: Other users experienced a similar problem on earlier iOS versions which is commonly known as the toggle switch issues - check thread here - https://discussions.apple.com/thread/7219001. Is anyone else experiencing this bug in iOS 14? Any solutions or work arounds?
