Ok, I have a pdf viewer control, and its working pretty good. However, It only views in landscape, and is not tied to rotation of the device. I want my page to be portrait mode, and still be independent of phone orientation. I find there is a "Direction" prooperty for gallary, but not in PDF Viewer. Any help with this?
I think this cannot be changed so far for PDF control, see below documentation about PDF viewer which does not contain the property about Direction:
You could post an idea in the PowerApps Ideas forum, so it might be considered for future releases.
