Just got off the phone with ProSeries to inquire if they intend to fix this issue since the issue is still present after the update that "fixes" was released on 7/26. The agent said ProSeries will NOT fix the issue and will only do the work around of disabling/uninstalling KB5026446.  The bug in KB5026446 was resolved with KB5027231 on Microsoft's side. This is poor customer service and programming on ProSeries's side to not find the root cause and fixing it. Please get an update out that will PERMANENTLY fix the issue with 2021 and prior years.

What's even more frustrating is that the MSI will have to be installed and configured on any new machines, something that should not have to be done.
