Update to an approved app keeps getting 4.3(a), no details given

Hi,

My app Stiktl (Apple ID 6782665395) has been on the App Store since July. Version 1.0.2 was approved in September, but that build shipped with a .NET MAUI framework bug that freezes the app when people import stickers on iPhone 12 and newer. I fixed it right away, but every update since then gets rejected under 4.3(a) with the same generic text about sharing a similar binary, metadata or concept with other apps.

It's the same app, same code, same developer. I'm a solo dev from Mexico and I wrote it myself, it's not from a template and I don't have any other apps. Right now users are stuck with the broken version and I can't ship the fix.

I already changed the store text and screenshots back to what was approved, replied in App Store Connect, and filed an appeal. The answer is always the same template, so I don't know what to change.

Could someone from App Review tell me what exactly is being matched, and with which app? I'm happy to change whatever it is, I just need to know what it is.

ThanApp Reviewks, Arturo
