So, It is not working on new or renewing. We don't allow anything but manual renewal. The other part of this is that it was all working until the upgrades.
Nothing in spam/junk, which is typically where these go. No additional updates or installations were done to other parts of the site, just the update on CBSubs. We use this to menage membership for this client, so the features we use are pretty basic. We don't use expiration or cancellation in the system since we have to do that manually per their agreement. Its freaking weird!
