Let’s think that i had bought a app i mean i had purchased it, then suddenly i regret i had wrongly purchased it or i don’t needed it. I requested an App Store refund for an app that i later realized i actually wanted and needed it.
It was really odd, i encountered a weird error telling me that since I had previously requested a refund for the app, I could no longer purchase it again. That makes no sense. Why would Apple not want to take my money just because I had requested a prior refund?
So whatever the reason for this error, i started google searching and i found a good news is that fixing the Redownload Unavailable with This Apple ID error is very easy to do…
How to fix the Redownload Unavailable error in the App Store:
Step 1: Open Settings → iTunes & App Store
Step 2: Tap your Apple ID
Step 3: Select Sign Out
Step 4: Open the App Store, and try to purchase the app again
From there, you’ll be requested to log in to your Apple ID account again. After you login, the App Store should allow you to download the app that was previously off limits.
So the end point is it just takes a quick sign-out and sign-in to fix the Redownload Unavailable issue. Yes, it’s inconvenient, but I can attest that it works. Have you ever encountered this error?
