@Ruhan_Miah It’s been told that the issue not related to ClearText Traffic multiple times.
The reason your account got terminated is because of some automated play store check that your account got flagged for. You can either appeal once if you think you have done nothing wrong and is in the right. Take your time to write a proper appeal to Google Play.
If there is no positive reply from Google, it doesn’t matter if you actually violated the Google Play policies or not just because of the monopoly Google has, there is nothing you can do about it.
Google does not care about small developers at all. Unless you have a huge following and backing to make it an issue on some social media they don’t care. If you have local government laws favoring consumers, you can take it up to court (that is a whole different story).
