I'm trying to restore my premium upgrade, but the app says "Restore failed". ← Pillow Premium The "restore failed" message usually signifies a temporary App Store glitch and the restore completes successfully when trying at a later time.Unfortunately, the transactions are handled by the App Store and not directly by the developers, so we are not able to fully troubleshoot the issue. Apple has in place a guide for failed purchase restore at https://support.apple.com/en-us/HT204530.
