Android Build Package Name Now Must Follow Convention 'com.YourOmpanyName.YourProductName'

My game package name format is ‘CompanyName.ProuctName’ and its already published. And now I am going to start to use Unity 2021, But in Unity 2021.3 the package name must follow the convention ‘com.CompanyName.ProductName’ or it cannot be build. So how I update my game? While my game already use ‘CompanyName.ProuctName’ format. The last successful build was using version 2020.3.25f. Please help.

Version 2021.3, unable to build.

The package name of an Android app uniquely identifies your app on the device, in Google Play Store, and in supported third-party Android stores.

I have the same problem after updating unity from 2020.3.7f1 to 2020.3.34f1. The app is already published for a while so choosing another name is not an option. @Chzero have you found any workarounds?,I have the same issue after updating from 2020.3.7f1 to 2020.3.34f1. Is there any way to circumvent that check? I can basically no longer make a build for my app starting with this unity version.

@Hettinger Yes, the issue is that the application id that is already on google play (app/game is already published) can no longer be used to make a new build with a newer version of unity.

@Chzero have you found any workarounds?
