I have contacted Smash Balloons and they say Sydney is not allowing their code to size the number of lines shown in a feed. I deactivate all plugins and the feed doesn’t work correctly. I change themes to Wordpress Twenty Sixteen and the Facebook feed shows the correct number of lines that I have specified in their settings.
They have settings that allow posts from just me, from all or from just others. Those settings work but again the length of the posts is incorrect (too long).
In Custom Facebook Feed under Customize, typography, post text, maximum post length, this setting doesn’t work.
