Editor widget issues

Hey,

I've been trialling the product and I noticed that all the widgets in the editor (image, table, etc.) don't seem to work - they are greyed out and just "bounce" when I click on them.

I've seen there is a current issue with the Cloudflare API, could that be causing the issues?

Related to this - when the widgets are working correctly, should I be able to upload images directly in the editor or do I need to host on an external URL (which I think I need to when editing with Markdown only)?
