Yup. Got a few sales yesterday (across 3 accounts) and none of the emails came through. Got a couple today from yesterday. Got one from today but still a few missing from yesterday.

One thing I noticed - 2 of the emails I got were in a different format / layout to normal. Maybe the 'experts' are playing with a new format and broke something in the process

I normally get 2 layouts (I presume one for people paying from accounts and others from people using a guset payment or something) one has 'You have recieved a payment' in the subject line and the other has the item number in the subject line.
