Doesn't work with my Hero4 on my Pixel 6 Pro (didn't work with my Samsung Galaxy Note 20 either!). Rubbish coz I have a GoPro that's not much use to me and I used to use it a lot. Won't be getting a newer model either. I'll opt for something a little cheaper I think! There seems to be a lot of people reviewing in the same manner with the same issue and there's a standard response of 'we know, watch out for when we might fix it'. Not a great response - aren't new versions retro tested with older camera's before releasing? Legacy support is important for those of us that can't afford to buy the new camera every time one is released!
