When building the APK and trying to run it I get this error. Fmod - 1.10.00 when running with an old version of the Unity engine 2020.3.48f1.

Hi,

Just to confirm

- The Unity integration version:  
 ![image](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/7/7752d25cfa73ed5b05dc5fc88b02e6276da5fcba.png)

As `1.10.00` is no longer supported.
- Could I get a screenshot of the plugin structure:

So we can confirm that the file is in the expected location.

Could I also please get the full logs?

Thanks
