Alright.
I did have issues with the app yesterday because i wasn't getting confirmation of channels added or dropped but it was being done after a while. I added SS2 SD, SS2 HD, SS1 SD at 8:30 and dropped it at 10:30. I didn't get any confirmation but it was done. So idk if i can even blame them.
It depends on when u tried to add. Later it was getting added. I first tried and found the issue at about 5 pm. I believe it started adding after half hour or soYes, same happened to me, after confirming selection error message shows up but within a minute channel/pack successfully gets added
