Just spoke with SPS support who said, ""It is a system-wide error and the engineers are working on it. Once it's fixed, an email blast will be sent to all merchants.""
""Was an email blast sent to them alerting them of the issue?""
""I would hope so but you are my 82nd call since 4:55 ET so we have no idea. I suppose it would help to post something on the website but as I said, the phones are non-stop.""
Sigh....
