I'm assuming it's just a Twitch issue since they recently implemented the portrait versions, hopefully they fix it but who knows when that'll be... 🙃 Does the issue still happen if you don't edit the portrait versions? I haven't tried that yet...

So ironically enough, the one I edited today exported just fine, it's just a small group from a few days prior? So I'm not sure, maybe there was a fix between now and before, and perhaps those are just beyond saving now? I wish I knew what happened.
