I've also went ahead and sent an email. Let's see what sort of response I get. Hope the person that's fixing the issue isn't the one who has to keep stopping to answer emails! lol.
In the meantime, lost revenue increases due to this issue, really hope they will refund us once the issue is resolved.
Hope the customers who are realizing the issue aren't spreading the word to friends.
I'm also debating sending out separate Paypal invoices for shipping charges to each buyer with a note on the issue if there isn't a fix soon enough.
