I have a subscription expiring may but not able to use and edit my pdfs as I’ve always done. This is affecting my job what’s the problem

I gave a subscription that is active but I’m listed as a free user and can’t edit pdf files for my job I’ve been doing this the last year without any issues but today it’s not allowing me to edit. I’m far being on work what’s the issue this is frustrating . When I first got the app I may used it under Apple forwarded email but I tried both and the app isn’t allowing me to do my job today
