Instagram browser for creating an account

When i send our website link through Instagram. We have a problem when new users want to create an account with their email and password. They appear to reach to the user creation form, they fill it up but when they click “Create Account” nothing happend (see picture).

When you enter from another browser (not through Instagram) you can use the email and password to create a new user. Also when you enter through Instagram browser the auth0 front is different than from the other browsers (see picture below).

Thanks in advance for every response!
