Why is my appearance different on another device?
Your appearance choice is saved in this browser or mobile app, rather than synced to your account. Choose it separately on each device or browser. Switching roles or accounts on the same browser or app keeps its saved appearance.
A new browser profile or cleared app or site storage can start with System again. With System selected, differences between devices can also come from their own light or dark settings.
If you see a message saying your choice could not be saved, the current appearance can still apply for this session. Select your choice again to retry saving it. Until saving succeeds, it may not be remembered when you return.
