I am running into this issue (LinkedIn->share(): comment length is too long - max length is 700 characters.), when I attempt to auto post to LinkedIn. Funny thing is my auto post to LinkedIn was working just fine and I have not changed any settings.
Is there something that has been updated where I need to change a setting?
I reviewed my LinkedIn app settings as well as my EasyBlog auto post settings and all appears ok.
Let me know if you would like backend access.
