I have bought Pro a couple of days ago and installed the Windows App. Everything was fine. Today I decided to do some reorganizing of my tasks with my PC being offline. After I connect my PC again, the app is not syncing, saying I need to renew Pro membership. After a number of attempts, I tried to log out and log in again (surely losing all the work I had done this morning, which is really annoying) and it still says the same thing. However, on the website, when I log in, everything is fine and it says I have a Pro Account. What do I do?
