I have implemented R8 Obfuscation in KMP project...It is not keeping my data models and domain models in android side .. i also tried defining the proguard rules but didn't work... The error i get is AbstractMethodError...Can anyone help me out with this. Strange is that it works on most of the devices in release mode, but some devices like Pixel 6A it gives me the following error. And yet on the same device it is not constant for all of the APIs and screen. On some screens it works fine but on some it doesn't.
