My people can't see my feeds

My people can't see my feeds

Hi I am the super admin user for my CRM and I have put to share my feeds to the public (i mean to my people already) however, all of them just can't see the feeds on time.

Specially there have 2 person- standard user but i realised their feeds is blank, nothing is showing.

I have do all setting from FAQ but it still couldn't work.

The support team just couldn't work.  They are telling me thing which was not that useful.

Does any people could give me a help there?
