Screen Controlling Friends’ FaceTime Screen (IOS18)

Hey! Me and my friend were on FaceTime, and I recently had downloaded the IOS18 update. We had realised when we screen shared we had the option to go on each others screens and control it (which we found really cool!), we were messing around until my friend glitched out of the call (when she was controlling my screen) and when she came back we couldn’t control each others screens :( Someone please help we were having so much fun and there’s nothing on google or reddit or anything for advice 😖😭
