I am running the SS contributor app on an Android phone and its working this morning - where "working" means it gets muddled about when "Today" is, but I can see sales for Wednesday May 22
I have been asked about liking the app a lot lately, although I don't log in unless it forces me to, and it hasn't done that in ages. I always say "no" because the bug where they are wrong about "Today" has been around forever and they can't be bothered to do anything about it.
Is it possible you're using an iPhone?
