cannot get fullscreen to Windows 2012 R2 on APM webtop

Was there ever any clarification on what the root issue is here? Is in fact disabling "NLA only" the correct fix, if you don't want to configure an app tunnel?

And Zup, could you post your step-by-step for how you configured an app tunnel as a workaround (or point to the guidance you used)?

thx! I'm going to post my (similar) situation separately, but thought this discussion could be relevant to my issue as well.
