New update didn’t fix any of my issues but now there’s another one.
Issue of sending to Facebook just picking any old image still remains. The option to choose which image to send to Facebook never worked, but it doesn’t even restrict its image finding to the blog post. It posts random images from the entire website just based on it being square and a size it likes.
Another issue is that the message format doesn’t save now, new issue since the update. It will only keep the message format if you press post to network inside the blog post. But if you press publish and let it do that itself, it will use the default message format.
