Restore does not work, making the purchase void. – Sobotta Anatomy Review

I bought the Sobotta app when it surfaced, but now it is unusable. It gives an alert to contact the developer because it does not work with the current iOS. I downloaded also the newest Sobotta app, but the restore purchase button doesn’t work either. It would be nice to find help to be able to use the purchased app again.
