[iOS Remote] PowerPoint Problems

Seems loading PowerPoints while using the app lock up the preview and it stops changing. When going live with a PP, I tend to get a black screen on the preview in the app. I can still control it, but the preview is black.

PowerPoint would be one of our biggest uses for this app for when presenters want to control their own. Hopefully this can worked out.

FYI I am using the second version of the app.

Using PowerPoint 2016. As it is now, No PowerPoints will show in the Preview Window. I can see all the slides and can change them, but the preview is black. Happens on all PowerPoints.
Are you still having this issue after a system reboot?
Can you attach a schedule you are using or email it directly to me?
Which version of PowerPoint are you using or are you using the viewer?
I cannot get PowerPoint to preview at all anymore.
