We have an old Android app, last released in 2019, and I have completely redeveloped the app using React Native. Additionally, we no longer have access to the old source code. I want to release the new version as an update to the old version so that our customers can directly install the new version via an update.

Unfortunately, this isn’t working. Whenever I try to release the new version for testing or even for production, the release gets rejected because the old 2019 version uses a non-compliant SDK version. I don’t want to use the old version at all; I’d rather just remove it. I’m stuck and can’t find a way to release my new app because the old app always leads to a rejection of the release.

Can someone please help? 🙂
