Customizing Confluence cloud pages doesn't work

Question

Hello,

We followed the official Atlassian documentation for theming in Confluence Cloud:
https://developer.atlassian.com/cloud/confluence/create-a-confluence-theme/

We created atlassian-connect.json, deployed the app, and selected it in the Themes settings.

However, we encountered the following issues:

* lookAndFeel properties do not apply.
* There are no requests to /rest/api/settings/theme in DevTools → Network.
* AP.request('/rest/api/settings/lookandfeel') does not work.
* We also attempted to use Forge with UI Kit and Custom UI, but none of these approaches allowed us to apply custom styles to Confluence pages.

Can you confirm whether confluenceThemes is currently supported in Confluence Cloud?
If not, is there any alternative way to apply custom styles at the space level?

Thank you!

heh, thank you for response. yesterday, they removed a note that it might not work with the new UI, but seems like it don't work with it

@Valery Sverdlik Just a note. When I opened the page you provided a link to, it says that it was last updated today (Feb 24, 2025). You might want to check to see if they updated something that changes what you need to do to make it work.

Edit: Or there is a possibility that the themes feature is not supported with the Free plan, but I don't see anything indicating that.
