Hey @userpiBM5QjrBl ,
I'm sorry, you are having issues with your google play store. You can try reinstalling the play store app here is a link https://apkpure.com/google-play-store/com.android.vending/download?from=details
I hope that this helps if it does leave a like and mark accept as a solution.
I am having the same problem with my Samsung Galaxy S10. All of a sudden, and I want to say it was after a recent Andriod update, the Google Store stopped allowing me to download apps, with or without Wifi being on. Interestingly, however, when I go to a friend's home there are no issues. Thoughts? I have already cleared cache many times, and have once made the mistake of clearning data...won't do that again. Thoughts?
