I find this happens often. No problem with me being A list, but with my companion. I usually wait until T + 5 seconds before trying. Then often get that message 2 - 3 times before getting the BP screen. This usually take me about 3 seconds per try, so 3 tries can be at T + 17 seconds and often results in A 40 or so.
I wonder if the computer gets hit with too many requests at same time and bumps some out.
Is it best to use back button? Maybe should open 3 windows with info typed in rather than using back button?
