These guidelines are easy to read and understand.
Tinder error 40303 basically means that many users have reported your account due to which you have been banned from using the app.
A few months ago, I had an account immediately get shadowbanned because I got lazy and started it with an Android phone connected to a Google Play account I had previously used to make a purchase.
You might get away with the latter, but keep in mind that if you get banned, they might have been the reasons.
In this case, you will need to create a new Tinder profile.
Anyway, just wanted to tell you that I created a new profile using only my phone number.
