Thank you for your feedback/review. I tested at my test site and it works normally. When I type something I can see the Post Update button. Maybe there is a plugin conflict. Can you perform plugin conflict test? You just need to deactivate all the plugins except BuddyPress and BuddyPress Activity Plus. Is that working after that?
I have the same issue. Well sorta. I’m using the Divi theme. I did the plugin test and it still does the same thing. It is not that the button goes away, because the button turns to Add Link or Add Video. The Video works consistently, but the link almost never works. It used to work awhile back. Not sure what happened. Can you help?
