A Published Post Not Appearing In The 'Stream'

I have published a post here :
it is published and viewable - scroll to the bottom and you can see 'previous post' - https://beyondbridges.net/2018/04/amazons-a-to-z-needs-to-catch-the-magic-of-alibaba/
which you can get to - but notice that you can't now go to 'next post' - moreover if you simply go to the stream here : https://beyondbridges.net/
then https://beyondbridges.net/2018/06/in-praise-of-micro-blog/ isn't even visible!
Is there anything I am missing - the post is marked public - doesn’t make sense at all to me ...

the amazon post is the latest and
