I'm having this same problem in my published app and I don't know what I need to do to solve it, could someone help me?
In app add on purchase fails with PEX-CatalogAvailabilityDataNotFound error
Hi!
I have an app, already in the Microsoft Store ("JVElaser"), for which I've never managed to get add-ons in-app purchase to work. The add-on ("Win.Laser3D") is also in status "In the Microsoft Store".
Within the app I see the correct store price (₪56 ≈ $14.99), so presumably any linking works, but an attempt to actually purchase results in the windows popup and after entering the password, the purchase fails with PEX-CatalogAvailabilityDataNotFound qG1gLIKEUkKVv5 + F.4.3.1.2.1 2021/03/15 - 10:30:09 UTC.
Googling says that this is a local store app problem, but I've tried reseting the store locally and tested this on several PCs with multiple Microsoft accounts.
If someone wants to reproduce, download "JVElaser" from the store, choose "Open Graphics" and choose some image, if it's large enough disclaimer at the bottom will appear. Click "Details", then "Buy". Windows will ask for your password and then fail.
Any help will be appreciated.
Thanks!
