I just tried for 15 minutes to include an image, both from a "helpx.adobe.com" link and by downloading/uploading via the image dialog (button indicated below, you know the one). Neither worked, but when I just pasted the link into the post, it rendered just fine. 🤦:male_sign: It would render in the dialog, then just insert a blank line in the post, or render in the preview and then the final post would be sans-image.
On Edge (😅) Version 80.0.361.66 (Official build) (64-bit), so the new Chromium based one.
Oh look, the image is missing...imagine that. Clearing browser cache and trying again.
Hopefully the image posts successfully (left of this text), if not then there is a bug in the post editor. If so, I'll just delete the thread.
Okay, clearing cache solved it. Leaving this (despite what I said before) for reference.
Mods: feel free to delete it if you think it is unhelpful or redundant to other info.
