The preview program is an opportunity to help test our new features early and give feedback or suggestions on it; however the version you get to use can possibly be buggy or incomplete. Before starting a series of Preview updates, we encourage users to perform a manual backup of their settings by heading to Settings -> Advanced -> Backup Settings. To join the preview program, head to Settings -> Advanced, toggle the "Update Preview Program" option, and restart Mix It Up to update to the preview version.
For any questions or support regarding the preview program, please join our Discord Support Server and use the #preview-program
channel.
