To be clear, this is a great company, their customer service is top notch, and just the fact they give unlimited free access to free VPN servers is awesome. However, despite the best efforts of their support team, I still encounter an issue where I am disconnected once a day, despite having 'always on' VPN enabled, the app 'pinned' to multi-tasking, and various other settings on my phone and AV. I would give it 5 stars easily, but with this issue, to get the dev's to see, I've lowered it.
