the problem seems to be with the auto update mechanism, if you uninstall and then reinstall from a freshly downloaded version it still says 0 cloud users, but all those errors are gone and it works correctly.
Same here, even at 300% the window is still tiny, the font is barely readable. Tried compatibility troubleshooter and all the options for overriding the default scaling behavior no change. I've had a similar problem with another program that was fixed by overriding the default scaling behavior. Good to know it's being worked on.
