As you probably know, you can move points between your Starwood Preferred Guest and Marriott Rewards accounts freely with each Starpoint equaling 3 Marriott points. Until recently, all of my transfers from SPG to Marriott appeared instantly. Today I transferred 40,000 Starpoints to Marriott. However, when I went to the Marriott website to complete my booking, I still saw a balance of 488 points. 
The mobile app on the other hand showed the correct balance of 120,488. So what gives?
The good news is the transfer worked. However, your web browser is showing a cached page instead of the updated version. And luckily the solution is simple! All you need to do is clear your cookies and the browser will refresh.
Final Thoughts
It can be nerve-wracking when you send Starpoints to Marriott and you don’t see them show up in your account. Luckily, the transfer is still instantaneous, your browser just may need some time to catch up.
