Solodigitalis Community Support

Hi, I’ve been using Soloslides to turn my old iPad into a digital frame. I wasn’t able to upgrade to premium on the old iPad so I used a new one. Back to the old iPad, I couldn’t restore my purchase. I am quite sure I used the same ID. Could you please help me?

I'm afraid this is outside of the app's ability - this is iOS itself. You'll need to talk to Apple.
One thing I can tell you that's confusing is that on older versions of iOS such as the one you're likely using on the older iPad, there can be multiple Apple IDs signed in the same time. You need to specifically check for Apps: open the Settings App and find the apple id signed in for App Store...

Understood. Indeed I checked the ID on Appstore and it was the right one. I managed to solve the issue by deleting and reinstalling the Solo Slides app.
