I had some issues with color palette not working on the 1st beta. Like the alert slider or the brightness slider not changing color. Just small things. Since 2nd beta though all is working okay. Have you tried clearing the cache for One UI Home plus a reboot?
Please try force stopping the app, clearing its cache and rebooting your device. If issue continues, please send us an error report to help us debug the issue. We apologize for the inconvenience and appreciate your contribution to the beta program.
