All TestFlight builds for my app expired at the same time, overnight, with no action on my side. New builds upload fine and show “Ready to Submit,” but: Internal testers (and I) cannot install: “The requested app is not available or doesn’t exist.” -Submitting for external review fails with 422: PARAMETER_ERROR.REQUIRED / filter[build]. Internal testing worked perfectly before and broke overnight. This appears to be a known recurring backend issue. All agreements, banking, tax, and export compliance are Active. DSA declaration is currently In Review. I’ve opened a support case (aprox. 5 days ago, only automated reply so far). Has anyone resolved this, or can a DTS engineer help escalate? Bundle ID available on request.
