New Plex Windows App - Scaling issue for 4K Display

Adjusting environment variable made no difference to me. Using Sony 4K although other apps don’t have this problem plex is unreadably small. I have tried the environment variable with and without spaces between variables and restarted entire computer, no difference made so really hope this get sorted. In my excitement I uninstalled the app store version and don’t want to have two plex apps.
