I can't download any app from App Store using iOS 8.3

IF you explain what happens when you try to download apps, it might help, but in the absence of any further information from you, try signing out of your ID, restart your iPad and then sign in again.

Settings>iTunes & App Store>Apple ID. Sign out. Restart the iPad by holding down on the power button until the slider bar appears, then slide to the right to shut down. Hold the power button until the Apple logo appears to power up again. Go back to the settings as described above and sign in again. Try to download apps. If that doesn't work, post back with your results and provide details.

I think I am having somewhat of a similar issue. I cannot log into the App Store or the iTunes store on my ipad Mini (iOS 8.3).

It is definitely not an issue of the wrong Apple ID or password since:

1. i used the same Apple ID/password to log into this forum;
2. I can log into FaceTime using the same Apple ID /password on the iPad mini;
3. I can log into the App Store through iTunes on my mac . The account information, including a positive balance, is correct;
4. I don't get the "Could Not Sign In Your Apple ID or password is incorrect" pop up on the iPad mini as i do when i purposely put in the wrong password.

I have tried to sign in on the iPad Mini a number of ways, all with no success including:

1. Settings > iTunes & App Store. The Apple ID is correct and password box is greyed out and says "required". When i type in the correct password then click "Sign In", nothing happens other that the color of "Sign in" changes form grey to blue.
2. in the App store App in the "Featured" tab at the bottom, clicking on the "Sign In" button cause a pop-up box. After choosing "Use Existing Apple ID" and filling in the correct Apple ID and password then clicking ok, again nothing happens.

After googling for possible solutions, I have tried the following without success

1. Cycled the power on and off as suggested above
2. Cycling between setting the the time between manually or automatically;
3. Settings > General > Reset > Reset Network Settings;
4. Syncing in iTunes with Computer

Settings > Restrictions is off (although i also enabled it but allowing "Installing Apps" to no effect)

Any suggestions short of a factory reset then restore from iTunes on my mac would be appreciated

So? have you solved the problem? - I have the same one....

NO solution yet. We are not the only ones with this issue. It is also discussed in this thread

I have the same issue since updating to iOS 8.3 on my iPad Mini 2 (A1490).

i tried all the recommended fixes on this thread with no luck.

Any further suggestions will be greatly appreciated

Same problem here. I think this is an apple problem and nothing to do with my iphone

Have you tried wiping your iPad and resetting it up. It may work not sure? I had this issue and I just erased everything and reinstalled the IOS via iTunes. It seemed to work.

iPad A1395 iOS 8.3 don't runs YouTube nor 1Password. Why? How to surpass?

PLease beeserdad, if you solved this problem tell me how. I have the same the exact same thing on my iphone 5s

This has not been fixed. I was hoping there would be a solution short of factory reset then restore but that seems to be the only thing that I haven't tried that is reported to work.

I Have the same problem with my iphone 6plus ios 8.3

Problem solved by restoring my iphone and setting it as a new device.

I didn't try to restore from a backup though.

Hey i managed to solve this problem. Is anyone interested Or still have this problem?

Certainly you should share your solution. You don't even have to ask. It could help someone else in the future even if it doesn't help anyone here.
