Hey Chelseacatty, could you test the A400M and A321 from your side? Although it is now possible to log in, the A400M and A321 have low frame rates and the A400 itself has extremely low frame rates. As with both the Beluga and the A400m, trying to set the Simbrief ID on the EFB causes the controls to lock up. Of course, I am using Xcloud, I believe you are on the Series S, but the effect will be identical.
We will keep this topic open until the patch arrives tomorrow (or Tuesday) and then we will ask again if there has been any improvement in this issue.
