Don’t worry, it sometimes takes a while for payments to process. However, if you do not have access to Pro features an hour after subscribing, please sign out of the desktop/web apps, and sign back in.
If that doesn't work, please click the big question mark in the bottom right of your screen.
If you have bought your subscription via App Store, then try to restore the purchase in the Mac app (go to Preferences > Upgrade).
If you need further assistance or have additional questions, we’d be happy to help! Please contact our support team at email@example.com.
