FB Feed not retaining configuration and not updating

Hi

I know as a paying customer I should be posting this on your site but your forms are failing during submission

I am having trouble with FB feed, as FB groups are no longer allowed to be scraped under your advice I have created a new feed and configured to our FB page. I get it up and running and after an hour or 2 it 404 errors also the feed its self is not updating. I noticed someone else on the support forum was having the same trouble and it was suggested to try a different theme and do a plugin test which I have done the errors persist

My feed is published here https://poetry.org.nz/facebook/

My FB page is here https://www.facebook.com/poetryorgnz/

By comparison its not updating also when it displays content

I really purchased the plugin for the FB group feature as that has a lot of activity for us over the FB page do you have a solution?
