Beta Expired Message?

Git this message for the first time (1 hour before live gig start). Does this mean the beta program for testing new features is over and I’m back to 2.5.3 from last year?

Yes, unfortunately. I had the message a view months ago. I think I had to reload the stable version from the App Store. I Don‘t know, maybe there is an update in TestFlight so you can download the Beta again? But I don‘t think so… Normally the Beta versions expire 90 days after publishing.
