Rose Connect Windows app Screen size

Having used the Connect app for Windows as my usual control method, I have recently found that the screen format has changed so the entire page is displayed and the text size is so small as to be illegible.
I have changed the display settings on Windows which affects the display of other apps but not Rose Connect.
Everything works fine as previously on i-pad and android phone.
Seems to be an issue with the way the Windows app formats its screen display.
Any suggestions?
