What is going on these days? About 6 months ago, I transferred 25,000 SPG points to topbonus and the transfer went through in a couple of days.

Recently, I initiated a transfer of 1,500 miles from the Marriott program that took 8 weeks! This was longer than the Marriott program stated the transfer would take, so I emailed them, and they had to email their AB representative at least twice to get moving on the transfer.

10 days ago, I transferred SPG points again, and they are still not showing up in my topbonus account. I am still within the acceptable window, but this is slower than last time I transferred SPG points.

Given that there is a slow transfer from two separate programs, I wonder if the problem is on AB's end. Has anyone else noticed this? What could be the cause?
