Not receiving recent Figma updates (UI3, Slots) on both main and beta app

Hi ​@Heath Dyer, ​@Badredine Aniba, and ​@David_Galliford, thanks for following up here! 

As mentioned above, we’re still gradually rolling out the new left navbar to users. This rollout is happening at the user level (not the team or organization level), so it’s expected that people within the same team or organization may see different experiences for now. We understand this can be frustrating, but thanks for your patience while the rollout completes.
 

Regarding Slots, this feature has already been fully rolled out to all Full seat users. If you’re unable to access it, try refreshing your design file, confirming you have edit access to the file, or creating a new main component. For step-by-step guidance, you can visit:

If you’re still having trouble accessing Slots, please feel free to let me know!
