Everything is working great via VPN. As Awisefew says HD can lag if you have slower than 6Mbps. I am using this app with iOS 10 beta with no issues. As I rely on data stored in various apps on my mobile devices, the choice of device capacity will play a big part in my choice of new mobile device, in my case iPhone 7. I moved from the default 16GB available on most seat devices to 64GB but now even this is not enough. 128GB will be my new normal. As I type this the Channels app crashed on my iPhone 6s. This was due to the capacity of my iPhone becoming full with the data stream. I have not looked to see if there is an option to switch off the timeshift capability.
I would like to request some features.
Favourites synced between iOS and tvOS
Be able to set timeshift buffer size or time.
Other features that come to mind are more directed at the DVR side. I will post those there.
Note: With more and more services configured on the home network needing to be accessed from outside the home, my ISP’ upload speed is playing and equal role to the more talked about download speed.
