It won’t let me use my premium features it just says start free trial for Adobe Express

Hi ​@Kryptno, Welcome to our Adobe Express community! 

I’d suggest you check once by logging in to the Adobe Express webapp from the same Adobe ID you purchased the subscription with. 

You may also want to sign in at https://account.adobe.com/plans and check for active plans on the account.
