Hello, Commander!

I have tested the feature according to your steps, but the bug has not been confirmed. 

I have the same problem. after one click & hold to navigate any subsequent click & holds move the screen rather than the map. i'm thinking it has something to do with either the game or systems thinking there are multiple displays attached as this is what happens when you want to move a screen to another monitor. the only workaround i have found is to lick a tile and close it then you can navigate for 1 click & hold. this is not satisfactory as it makes the game nearly unplayable, but it works for me.  maybe they will actually address this issue as many people are having it and posting about it under various thread name.
