I have an app for which I can create a custom export which I can then transfer over Airdrop.But my device running iSO 13.1 is no longer able to accept the incoming data. The device seems to receive the incoming transfer, it vibrates, but then won't open the app.Also in a share-sheet (for a version of the export I sent over WhatsApp) my app is no longer shown.Any idea on what I can do to fix this?
