Every time I launch Fresco the preferences are reset to default, and it's very annoying. It will change from Dark Mode to Light Mode, finger input goes from Gesture Only to Draw with Brush, etc. It's very very annoying having to re-setup my preferences every time I launch the app. The app always closes properly, so it should be saved. I am using the latest update for both Windows and Fresco, reinstalling doesn't work, and restarting my device also doesn't help.
Any chance there has been an update which has fixed this issue for you? If not, I would suggest using the bug report option within Help in Fresco and sending the Fresco Developers a direct message. Using the link in the app will create an email with your systems details in it. This may help them to target your issue on your device more directly.
