Did you try to put the export of the FTA's in the local profile and let it be saved by UEM? I created a description in a blog article.
The Set/Get FTA commands have changed along the way, but the principles are the same.
I did not attempt to do it this way myself, however a co-worker did. It wasn't working at first so he attempted a different way.
It seems though in the process of fixing a different issue (I had to bake the GPO ADMX template for the Flexengine into the base gold image and configure it, as GPO was hit or miss applying to the machines), it may have fixed this. I created everything as you did on the website and everything is working like a charm now.
Thanks very much for your assistance. Glad to see a longstanding issue has been resolved.
Good to hear that it works now and thanks for the feedback!
