I ask for the same

I would love this feature. I was paying for a subscription, but discontinued because I'm not really using all of Restreams features. I would love to duel stream, but also in Vertical on YouTube. The main reason is, I don't have the best internet. I have Starlink, but it's absolute garbage with upload speed. Restream has been amazing for duel streaming. I read the forum here that said I could create two accounts to stream in landscape and vertical as a "workaround" but also confirmed with your staff that that would take twice as much internet. I've tried using plugins with OBS, but it almost always breaks the stream in one way or another. I would also jump on an opportunity to be apart of any beta testing, if available.

The ability to stream in 16:9 and 9:16 at the same time (example: for PC and phone).

Yes please
