we have 5 users with a 5TB plan, now gone over that, so I upgraded our account to be the limitless one. Dropbox in the system tray still shows red X and cant sync because drobox is full. Problem consistent across all users. Is there another step I need to take? The payment went through and on my account it says we have the limitless plan (Business Advanced). Surely it cant take more than 24 hrs....?
