Well this has been an issue for a long time since it was Windows beta version. Each time I could hardly download unless I use VPN.
Then I decided to purchased Designer and Photo for Windows version through Affinity Store as the applications are just what I'm looking for.
However, the download source is still not friendly to Chinese users - the download is slow down to 20KB/s around and it often hangs and interrupts so I still need to use VPN. The download could be done within 1 minute under VPN network.
I don't know if this is related to Great Firewall but I hope this issue could be resolved since I have paid.
If this could not be resolved, I wonder if it is possible to transfer the license to Windows 10 Store version because I can download the apps from Windows Store smoothly. No need to worry abou any interruption or proxy.
