can't log in to android app

I have the Musescore app on my phone (Samsung Galaxy A22), and a couple of weeks ago I randomly got logged out of the app, got no idea why. Now, when I open the app to try to log back in, it won't give me the option to log back into my already existing account that I have used for years (on this phone, previous phones, my current and previous laptop and my tablet). It instead takes me through the whole rigmaroll of creating a new account, asking what instruments I play, what genres I like etc, and after all of that, it gives me a graphic that just tells me what my free trial will incorporate (see picture). I get no option to close this graphic other than the "got it, thanks" button, which I assume gives me a free trial (which, by the way, I don't want) and as I said before, I get no option to log into my already existing account. I've uninstalled and reinstalled the app I don't know how many times by now and every time, I keep getting the same process and the same lack of options to sign into my existing account.

If anyone has any solutions, please, I am begging, give me them, this is so frustrating.
