I got a replacement RE500 range extender for my vision. Trying to bind it and am having trouble. I turn it on, reset it and then can connect to it on my phone. When I go to the binding section in the app it won't allow me to scan the QR code. Just says that access to camera is explicitly denied. Ok so I just manually type in the MAC address for the camera then hit the blue check and it goes through the binding process. The range extender restarts like it's supposed to but after it has restarted my phone will no longer connect to it unless I restart it again which leads to starting the whole process over. I've read similar posts but can't find a solution in the responses. It seems to bind like it's supposed to but when it restarts it's all for naught. Any ideas? Thanks in advance.
