Had so many issues trying to buy the Timelapse app for my Sony A7Sii.
Wouldn't connect via usb to my pc at all. Didn't try on my Mac. Tried wifi and kept getting payment errors.
Finally tried adding money directly to my sony wallet from my account management and then tried buying the app directly from the camera wifi app and it worked!!
Sony really let the ball down on this one but at least I found the long way around to make it work eventually.
