This happens in version V22.214.171.1245 and is resolved with the following update.
The problem is usually the horizontal left-right movement after having entered the digital zoom, since the channel change is prioritized over the displacement within the same zoom.
- select only the camera of interest before opening its image, rather than selecting it from a group of preloaded video streams
- perform a vertical physical movement (up-down) and, without lifting the finger, perform the horizontal movement, which will already be done correctly.
A video clip follows to better understand the second option.
