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!

OpenVPN vs chameleon vs ....

The current protocol performs poorly at my work.

Please allow for faster server change. No need to force user to first disconnect then reconnect. If I want to connect to a new server then disconnection is implied. Let the app handle the disconnect automatically when I request he new server so that I only interact with it once without waiting for the first step to complete.

Also allow server changes from the drop down menu bar (Mac) without opening the full app window.

See Tunnel Bear for how they handle this. It’s easy and seamless.

You should add the "Connection Per App" function on win10, just like the Mac have.
It is very convenience to have this feature.

It would be nice to connect and disconnect directly from the control center in iOS 11

I have been having trouble with VyprVPN connecting. Found out I needed to switch protocols.

It would be great to have a protocol switch(es) on the control panel. Something similar to the "kill switch", "connect on untrusted wi-fi", and "block malicious sites".

I would also be great to have an switch to automatically find the "best" or "unblocked" protocol. You could set order of preference in the "system preferences".

it will be great to disconnect VPn connection quickly, rather than to have to wait a long time for it to disconnect, and shorten the connecting time also

Please add IKEv2 in the Windows and MacOS, and Android apps as a protocol option. Right now the IKEv2 is available only for manual connections.

For a website that supports Chinese, VyprVPN has become friendly enough, but I still find some functions to be promoted during use. If there is an automatic switchover, the function of the VPN line and the ordinary line will be fine! Use a browser to visit a foreign website or play a foreign game. It automatically switches VPN. If you visit your home site or play your own game, switch to offline-VPN automatically! That's a really good idea! Isn't it?
对于一个支持中文的网站来说，VyprVPN已经显得足够友好了，但是我在使用过程中，仍然发现了一些有待提升的功能。如果有一个自动切换VPN线路和普通线路的功能就好了！用浏览器访问国外的网站亦或玩国外的游戏它就自动切换VPN。如果浏览本国网站或者玩本国游戏就自动切换成offline-VPN！这真是个不错的想法！不是吗？

Please add a server in South Africa, this is sorely missing

Any secure messenger should at least be partially open source

Add obfsproxy for vpn block by firewall

Would be great if we could set a personalized text for the notifications when displaying the content of message is unchecked

Voice message like WhatsApp pls
