"The app is not installed on this instance."

Hi @MattS and @IWSAdministrator ,

Can I ask you if this is happening with the new limited life/rotating refresh token or if these apps are still using the persistent refresh token?

For reference: Superseded: 31 January 2022 - Action required - Deprecating persistent refresh tokens

We are investigating what’s happening and this will help us in isolating the problem?

Thank you,
Caterina
