activitypub + wordpress.com

Has anyone been able to use this plugin on wordpress.com hosted website. based on my limited check the caching plugin on wordpress.com doesnt honor the “accept” header and if we ever recieve the html version of the page both html and json requests gets same page in response till the cache expired.

I am trying to enable it for my own blog and so far has been unsuccessful. the id does appears in fediverse on other platforms but follow requests dont reach me so i am assuming the plugin is not working as expected.

The page I need help with: [log in to see the link]
