VPN Client Pro

* Fix: Auto disconnect may not work when connectivity changes very quickly during VPN startup

The basic OpenVPN feature is free for all. To use other protocols and features you need to buy a license.

The requested permissions are used for these purposes:

* Camera permission is used to import VPN from QR codes.
