I am using TeamViewer Host 15.79 and my custom configuration is not being applied. Yes, Account Assignment is being performed, but the custom configuration is NOT being applied.
We have never had an issue before the latest version with the Custom Configuration.
I have seen the workaround posted for 15.78 -
CUSTOMCONFIGID no longer applies custom Host configuration, assignment still works - TeamViewer Community
I have tried the above workaround, but it does not work. I am still getting the generic HOST dialog.
