Figma Sites CMS stuck in View only mode despite being the file owner

Hello Figma team,

I am the owner of my Figma Sites file.

I can edit all my webpages normally, but my CMS collection is stuck in View only mode.

I cannot click the New item button or add and edit CMS content.

I want to use CMS for my My Moments page, where I plan to regularly publish personal stories, photos, and articles.

I have checked my file permissions and confirmed that I am the owner.

Could you please help me fix this issue and restore CMS editing access?

Thanks.
