Recording not working.

Even though the record function isn’t working, I am still giving this 5 stars. Extremely stable app, easy, simple, focus lock, multiple destinations, for free! Can’t get any better.

I noticed the app doesn’t ask for permission to access photos... maybe this is why it isn’t recording to the camera roll? (Or maybe I am doing something wrong)

Exactly what I needed

I've started streaming recently and have used this app 3 times for for up to 4 hours at a time with no issues. Pinch and zoom works well and I'm able to change the resolution through the app. Solid

Feature request - Multi cam support

App is great - probably the best no-frills live streaming app on IOS. Would be nice if the developers could add support for the multiple cameras found on the IPhone 11 and 11 Pro.
