I can't see my feed on my realm (IT STILL DOESNT WORK)

I've token quite a few pictures and shared them to the feed I only play on the realm because of the custom resource pack and behavior packs and they don't show up I even checked with my phone and I didn't see it I'm not sure if I'm dumb and doing something wrong

Ps sorry for the terrible image quality

 

Update it doesn't Work WHY
