@HelenaGeng I'm pretty sure it's a recent change in Apple's policies. Because I was able to upload v2.4 previously without issues. Would be great to have confirmation tho...
Also, @App Store Connect Engineer, what about previous versions?? e.g. I have a v2.4 TestFlight version. Do I have to go thought the TF review again just because you changed policies?? That's annoying.. But more importantly: What about AppStore versions??? I was planning a big "v2.4" release. What should I do now?
