Laptop - trying to logon using same username/password from phone app

Is there a way to use your username and password obtained from the app when we paid for the subscription, to then log onto a laptop ….instead of doing everything on the small phone app? I tried going to the actual website which is still in Beta on the laptop and I wasn’t sure if there was a way to log on? It didn’t seem to work for me.

Yes, just use the same email to login to the web app and you’ll have PRO.
If you anonymized your login while logging in with apple on your phone then things get a lot more complicated. If so, I would just login with a new email and DO NOT anonymize, and then transfer your pro subscription to that new account by going to the upper left menu on the home page and clicking “Restore Purchases”
