I have this happening on my Samsung Galaxy S8+. I can connect to my remote PC and everything is fully functional. However, after 2 to 3 minutes, everything freezes. The screen does not respond to anything in the app. If I disconnect and reconnect the session, I can just pick up where I left off. But then it freezes again after 2 or 3 minutes. It's frustrating. There aren't many settings in Microsoft Remote Desktop to change. I did change the sound to "Do Not Play". I flipped the setting for connect to admin session back and forth. It will freeze either way. Anybody have any suggestions?
