OP clearly states in the post they are using a modified APK to get premium access without paying

If you want to clear out any stopped containers, orphaned images, networks, etc run “docker system prune”

What I think is happening is there is a persistent volume mount that needs to be cleared out. If you’re using the docker run command with a -v flag, check the host path. It’s likely there are saved configurations you’re passing into the container.

You could try changing the user agent string in Firefox to make the site think you’re using chrome

Where is this magical cheese land you speak of?
