I spent hundreds on my camera and I can’t now use the app without having to watch adverts?! I don’t need your subscription and you are now forcing me to take one if I want to avoid them (which I won’t). Just because it’s a free app doesn’t mean you can add advertising, people have paid for a product, and an expensive product at that.
I would not have purchased this camera if I had known you were going to introduce this. I am not even sure you are allowed to do this.
I suggest people unhappy with this contact the retailer who sold it to them and look at refund options.
Completely out of order. You will lose customers because of this.
