Unable to resolve the 64-bit requirement for release

Hello

We are trying to submit our game for release and keep running into the same error message.

Error
This release is not compliant with the Google Play 64-bit requirement

The following APKs or App Bundles are available to 64-bit devices,
but they only have 32-bit native code: 10028.

Include 64-bit and 32-bit native code in your app. Use
the Android App Bundle publishing format to automatically
ensure that each device architecture receives
only the native code that it needs.
This avoids increasing the overall size of your app.

Here's all of the relevant information I'm aware of.

• We build using Unity 2018.4.7f1
• In player settings we have IL2CPP as scripting Backend
  and selected all Target Architectures, including ARM64
  
  
  
• We are building an Android App Bundle (*.aab)
  
  
  
• The installed NDK is version r16b, which should be the correct version for 2018.4.7f1 according to https://docs.unity3d.com/Manual/android-sdksetup.html
• Our build succeeds without warnings or any other difficulties.
• When uploading our .aab to Android Studio, the details of our bundle specify that there are 3 target platforms included.
• Upon verifying our product we get the error message quoted (and translated) above.
  
  

We have been researching this for the past 2 days and are at our wits' end.
Any help or nudge in the right direction would be immensly appreciated.

 

This question is raised quite sometimes on this forum.

Just disable x86 and submit. Unity deprecated x86 support in new versions.

 

Thanks for the help!
I just found other threads as well. I'm sorry for double posting.
