Studio Drums IAP won't install
Hi, I bought the new Studio Drums IAP a couple of days ago but try as I might I cannot get it to install. Bought 6th Aug (I have the Apple receipt email). When I try to install it fails with message like "Studio Drums: PURCHASE FAILED mzafbenc.[long number] couldn't be m...cause an item with the same name already exists." Any thoughts how to fix this?

Let’s start with the basics: fully quit all apps from the task switcher and restart your device. Does it still give the same error message?
Hi, yes, have fully restarted a couple of times with all apps closed fully, same result. On iOS 14.7.1 on an iPad Pro 10.5 (2017). Message is still exactly the same.
If I nose around looking for “mzafbenc” I can find the following Apple Dev forum discussion which to my untrained eye looks as though it could be at least partly related - the “m..” bit could be a truncated “could not be moved”.

However, I’m not an iOS dev so that could be a red herring.
I’ll report this to Matt and include your link. Usually problems with IAPs are in Apple’s court, but it doesn’t hurt to ask. If you’re getting near to the 2 week mark from purchase, I suggest you get a refund now so you don’t get stuck with a non-functional purchase.
If you feel like you want to try the ultimate solution, reinstalling NS would presumably get rid of any partial IAP installation that could be gumming up the works.
Backing up your work is easiest to do by using the Files app, making zip files of your NS folders and moving them out of the NS main folder. Or you can use webdav, but that’s been hit and miss for me.
Sorry to hear you've got problems with this. Ironically I'm involved in 50% of the Apple Developer discussion you linked (my user name's 'futile' as it's the word I most associate with trying to solve problems via the Apple Developer forums).
The problem as I see it is this:
It's stupid I know. I've had it occur once during development but never in the App Store version up until now. The only solutions I can suggest are:
Sorry, I appreciate that none of these are ideal solutions but they're the only workarounds I've found to date (this problem started in iOS 14).
🤣😂
Hi, my apologies for not responding earlier but have been swamped at work and frankly forgot I had raised this. Just remembered today that I had raised the issue, and have followed your suggestion including the backup. Restoring the backup was a bit of a faff (iOS didn’t want to uncompress to the original folder) but managed it eventually, but deleting the app and reinstalling appears to have fixed it - all purchases including the Studio Drums installed successfully.
Thanks for your help
Excellent! Thanks for the update 🙂
