It required an app to be installed on the camera that was paid-for. Which in term required the camera to be connected to a WiFi.
Imagine discovering this while on a trip in the jungle or the desert or whatever ...
It was a one time purchase (I think around 10€) but it was still a complete wtf.
You had to purchase the app through the camera's app store. You read right.
Ofc this failed as my CC was declined because I live in Germany and the transaction got marked as suspicious, coming from SEA.
So I had to go to town and hunt down a wifi USB dongle so I could turn my laptop into a WiFi hotspot for the camera, while using the VPN masking the built-in WiFi to be connected to a German IP.
You had to enter the CC details through the camera's on-screen keyboard that was operated with the joystick on the camera's body. It took me a good ten minutes.
No words.
