Has anyone managed to get their iOS app accepted eventually after an appeal got rejected?

You already got declined in the first instance (App Review) for probably a valid reason. You then got rejected in the appeal for probably the same reason. Why dou you think these were wrong? If you want in the AppStore you have to follow the AppStore Guidelines like everyone else. And no, vibe coding trash is not following the Guidelines - not the AI is responsible for following the Guidelines, you are.

It happens. But identical submissions isn’t wise

I mean can one get in if something changes by quite a lot
