Make the app always able to login EVEN IF YOU'RE IN CHINA
In china, you can't login to the app unless you've connected to VPN first by some other means. such as manual PPTP connection.
If someday PPTP is blocked in China like OpenVPN, what should people in China do?
So it matters to make your app ALWAYS ABLE TO LOGIN no matter where your location is. I'm pretty sure there will be some workarounds!
I was recently in the Beijing airport waiting for a connecting flight and I was able to connect using the airport’s free wifi and Vyper. I logged onto Facebook with no problem.
PPTP is not a secure protocol. I can’t imagine why the developers would implement it.
this is so essential and crucial for people who is using for the first time. they need to log in to use it. dev should pay attention on this. if we can’t log in then we cannot use it!
