Cannot Load Shared World

[wartherian]

I have a world I created and shared to some friends, recently been having an error pop up when I try to host it myself saying “Cannot Load Shared World; Cannot load a Shared World backup that is missing the primary save. This world may no longer be shared with you or has been deleted”

Ive tried reinstalling the game, the only way im able to load it up is if i am invited by one of the friends that has the shared save.

I have had a similar problem.  A friend and I have narrowed it down to the cloud saves not being accessible for me.  It is like I can send stuff out but, it won't come back.  The problem is we have not figured out a fix for it.
In attempts to debug this I appear to have maxed out the number of three shared worlds I can host.  My friend is able to see and access them but I am not able to access them.
