Thank you, Ryan_M for the info and the update on the investigation number.

When I called ProAdvisor tech support yesterday, the automated system sent me to QuickBooks Online support at first, not desktop support; and then it took quite a bit of time on hold before the tech was able to find the workaround for me.  Which is to say I'm not surprised that two others commented they were unable to get help with this issue.

The tech person I spoke with did not suggest adding me to a list of affected users, so that part is new, too, thank you. Though with how awkward the tech support phone system was, I must admit I'm not exactly inspired to call back in just to get on an email list.
