GOOSE VPN

The app is simple and I had a high hopes for it as they had 2 servers I needed the most - UK and Poland.
But after using it for a few months UK and Polish servers are not usable. First is much slower, and the 2nd one has been flagged by Google. Now every time when I want to use it I have to solve Google's captcha a few times - which takes forever.
Also the internet speed has decreased for me for some reason when connected to GooseVPN. And I was trying both IKEv2 and OpenVPN protocols.
I know of course that the speed will always be lower, but for it to be around 1/10th of the speed with no VPN it's just not worth using (my normal speed is around 100MB and with GooseVPN it goes down to less than 10MB).
