I have a problem similar to this question, but it is not identical.
- In my Android Build settings I have ticked "Build App Bundle.
- Scripting back-end = IL2CPP
- API Compatibility Level = .NET Standard 2.0
- Target architectures = ARMv7, ARM64, x86
When I build the AAB file and upload it to Google, I am given the error
The following APKs or App Bundles are available to 64-bit devices, but they only have 32-bit native code: 6.
When I build the game I can see the progress window saying it is building the 64 bit source. So why does Google keep telling me it doesn't contain a 64 bit version?
