Did you ever figure this out? I am getting a lot of Code=306 "Reached max retry count" errors in Production when users attempt to make a purchase. Apple can't fix/debug it unless I can provide a way to reproduce it.

I hope everyone is filing bug reports for this.

Still the same. See attached image of me resigning. The signature changes, but not the version.

Ok, I guess I fixed it, for now. Even though i'd tried rebooting the Mac, closing Safari then trying this login did in fact open Safari correctly. It even presented me with the 30+ login windows that had previously not opened. So it's working again now, but I don't know why it got stuck.
