The delay wait time is noticeable. DC's earnings fell from $ 52k to $ 47k.
Without data on DC income a month ago, two months ago, etc., it is hard to say with any certainty what the reason for the reduced income is.
However, improper DC decisions can not be ruled out.
I have just finished supporting the SS. Why? Because DC decided that the wallpapers will be available only from $ 10, and I paid $ 5.
Because the wallpapers were attractive to me, but certainly not worth $ 10 a month. What I was getting for $ 5 did not satisfy me, so I gave up SS support altogether.
There is a possibility that many players, like me, annoyed that DC for something as trivial as wallpaper, demands $ 10 a month.
Wallpaper which is probably 90% will be the evolution of something that was created for the needs of the game and making the wallpaper was fast and easy.
