Morning, I get the same issue with Instagram, it worked for about 4 posts and then I started getting that same error. It works in the settings as a test post but not in the actual blog post. I also tried re-posting one that worked before and now it won’t post.
I also get this problem with some LinkedIn groups (not all), they work as a test post from settings but not in the actual posts 🙁
I have raised a support ticket, fingers crossed I get a solution. If I do I will post it in here for you.
Thanks
Kerry.
