I'm having the same issue. The "use cellular data toggle" won't stay on for Spotify, Apple Music, Wallet, and many other apps. I originally thought it was only the apple apps that were affected but it's just random apps. It's very frustrating and hoping there's a fix soon. I have "use cellular data" turned on in all of the areas it should be, I've reset network settings, I've tried all of the tricks, still the issue is there.

I am also having this problem with my iPhone 6 plus. I really like the fact that someone send a tweet in Cook's account!


Also, I would like to express my dissatisfaction with Apple's many bugs that are continue to occur the last two years.... I like the fact that we have many !obvious! features implemented in every new release of both iOS and Mac OS but the bugs that exists in every new version are very irritating and are not fixed for quite a time... I am really sad for this drop in quality that Apple has lately...(and I am huge fun and user for a long time...)

Update on the Per-App Cellular Data Toggle Switch Issue:

A number of users, myself included are experiencing this issue.


Here’s a concise summary of the issue:

The issue concerns the cellular data app toggle switches in iOS 9. For example, when a user turns a switch "on"from an "off" position, the setting is not respected by the system. The switch will appear to change to "on", but if you try to use the affected app, it won't permit cellular data to go through. Then, if you go back and check the cellular data app switches in the Settings app, you can see that the switch has reverted back to its previous position, in this case "off”. Any users with cellular toggle switches in the "off" position before updating to iOS 9 now have the toggles stuck there.


There is an active thread going with users troubleshooting and posting updates. Feel welcome to join the thread and post any info you have and updates. You can find that thread here: https://discussions.apple.com/thread/7219001


So far, we have at least one solid confirmation that wiping and doing a clean install does not permanently address the problem. This suggests we need to wait for Apple engineers to find the issue, and issue a point update (think iOS 9.0.1) to fix the issue.


We'll need to be a bit patient because the process may take awhile, but calling in to Apple support and working with the techs may be helpful so they can collect more data. The more people that report the issue, the higher a priority it will be to fix it. Also, turn on the option in Settings to send Apple your diagnostic data (if possible). And follow the thread mentioned above.

Hi.


Found this thread searching for a fix for the same problem. I have both an iPhone6 and iPhone6+ and upgraded both to iOS 9 a few days ago.


SETTINGS-->CELLULAR-->USE CELLULAR DATA FOR:


(Apple apps such as Mail, Numbers, Keynote, etc do not "keep" configuration changes to "turn on")


I only have this problem on the iPhone6 and all is OK on the iPhone6+...


I think this is related to the settings above before the iOS upgrade.


Hmmmm


Hope Apple fixes this soon and I have to turn on WIFI to send and receive Mail with the Apple Mail app.


Cheers!
