First guess is that you are not actually getting the button pressed. Using your finger makes it hard to get the button pressed enough. I normally use a pair of needle nosed pliers (ones with a flat tip, not a point). You can also use a small screwdriver, machine screw, dowel rod, etc.
I had more than 1 pan v3 cams. I pressed them right. I used philips screw driver too.
Photos with finger just for demonstration that I have the cameras on hand, not trying to pushing Wyze under the bus as
they already have a big headache to deal with.
I posted because this problem give me a big headache since last weekend.
