License verification not working for in-app purchases about gmscore HOT 6 OPEN

More experimentation and observations.
LineageOS for MicroG 21 (Android 14) 20240416 panther (Pixel 7), Aurora Store updated to v4.4.4.

Without PlayIntegrityFix and PlayIntegrityNEXT, VTube Studio license verifies without issue but Quick Cursor's license doesn't verify.

Installing PlayIntegrityFix and PlayIntegrityNEXT Quick Cursor still doesn't verify, the error doesn't even occur so I'm assuming it's some incompatibility with Android 14 because it worked on 13.

I can confirm this issue. I meet it with MacroDroid. My log is in #2254 (comment)

Good news! I found a workaround that right now works 100% of the time but in the future will potentially not work anymore.

1. Uninstall all SafetyNet related modules in Magisk
2. Install PlayIntegrityFix and PlayIntegrityNEXT in Magisk
3. Download the app you want with IAP license verification
4. Tap the "upgrade" or "verify" option that "pays" for the IAP
5. See error "You already own this item"
6. Suddenly the IAP will go through and the license will verify
7. Cry (for happiness that it works and you don't need gapps or the Play Store)

Unfortunately this workaround requires Play Integrity to pass and this unfortunately is subject to change as time goes on, hopefully we'll be able to figure out something, MicroG has come a long way and I'm certain all these issues will be fixed.

This is referring to a feature (fetching licenses from server that were not purchased on the device itself), that is not yet implemented in microG at all.

Having some difficulty parsing what's being said here.

VTube Studio wasn't purchased on panther (Pixel 7), installing the two Magisk modules, the error still occurs however the license does verify when it didn't before.

I'm not sure why it works, would be great if it can be looked in to though.

Verifying licenses that were not purchased on my current device (FP5 with CalyxOS) do work now for me. As @videoman614, I still get an error message telling me, that I already purchases the feature when activating it. However it worked with aCalendar and Symphonium. I updated to CalxyOS 5.6.3 and updated Aurora to 4.4.4. Not sure which update fixed it.
