Discounted price and purchase prompt on iOS App Store
Solution 1:
I have this same problem on an iPad. If I uninstall the app I'm able to install the new version - but like you there are 10 apps I have this same problem with.
My suspicion is that these apps were installed when the iPad was setup to use Apple Account "A". A number of weeks ago I switched the Apple Account of the device to be account "B". So I think the problem is that the app store is preventing an app, installed by "A", being upgraded (for free) by "B".
Is anyone able to confirm this hypothesis?
UPDATE: Yes, this was my problem. I used the old account within the App Store and I was able to update those 10 apps.
Solution 2:
Finally, I overcome from this situation. All I need is to update my iOS. To me, it seems like it wasn't updated properly. Or it was stuck into "Insatall the Update" state. So I installed the update (From Settings > General > Software Update > Install). And now all pending updates are downloading.
Things I have tried but didn't work are as follows:
- Sign Out from App Store and Sign In again. (From App Store > Profile (Top Profile Picture) > Sign Out)
- Change Region and Reselect again. (From App Store > Profile (Top Profile Picture) > Your Name on top (It will move you into your Account) > Country/Region > Change Country or Region > Select)
- Reset Network (Settings > General > Reset > Reset Network Settings)
If you are facing this problem, you may try these, but didn't work for me.
