I'm experiencing a mild delay (Saturday submission), but I am assuming it's because I submitted more receipts on Sunday and more again yesterday (Monday). My understanding is that each time I submit something new, my entire text goes to the bottom of their queue. That's why typically, I prefer to do multiple submissions on one day....then wait until they are cleared before submitting a new one.
If you did not interrupt your place in the queue (as I described above), I also would be wondering & concerned.
Wishing you quick resolution!
