It seems like after reading a certain number of posts I have to log in to see the rest. Usually I don't bother. Don't see why the limit although admittedly there seem to be a lot every day currently.
By the way I don't understand the option between letting everyone see it (default option) or only followers in community as hidden post. I guess I should take the default option but puzzled at "in my community" as this isn't mentioned in "everyone". Maybe I'm just too old to understand modern social media fully!
