Hi,
I have purchased a TransMount Video Transmission Transmitter (AI) to use with my Weebill 3s + EOS r6 camera. Unfortunately, my version of the ZY Player app somehow doesn't show the controls for the gimbal which should be on the bottom left and the focus control square. The menu on the top right is a bit different from the ones I've seen on YouTube too. Because of this problem, I can't control my Weebill 3s with my iPhone while seeing the video and I can't use the tracking. I am able to control the Weebill 3s if I just connect to it via Bluetooth just like I would do if I didn't have a TransMount Video Transmission Transmitter (AI). I think something is missing from my version of the app. I am using an iPhone X by the way and tried the app with my iPad Air M1 as well.
