Hi, I've noticed similar questions to this, but they seem to have slightly different symptoms.
Every image I have attached from iOS displays the preview correctly, and even displays correctly while editing; the size of the preview can be changed, even. However, clicking the image shows:
Ouch! We can't load the image.
https://api.media.atlassian.com/file/1d1a4e47-45ab-47b4-a201-abb680e9cb9f/artifact/document.pdf/binary?client=...
Following the url gives something like:
{"error":{"code":"NotFoundError","title":"The file with the given id does not exist","href":"https://api.media.atlassian.com#NotFoundError"}}However, clicking the download button correctly downloads the image!
The JavaScript console gives a collection of 404 errors, and some about WebSockets connections being refused. I haven't attached the full output due to length.
I'm using Chrome 71.
