The error is:
SyntaxError: Unexpected token 'R', "Request er"... is not valid JSON
A smaller image, or different format, doesn’t make a difference. Not sure what to do. I tried with a 1536x2816 png, 3.93 mb; jpg version, 676 kb; and a 384x704 png version, 477 kb.
Is it still like this?
Yes, seeing how you asked this question I assume the fix is on the way or smth? (talking about video embeds)
