I've been trying to use ProtonVPN for a while, and the experience hasn't been good. For example, the kill switch doesn't work reliably (internet usually worked while ProtonVPN was not active), and lately also the internet doesn't work at all when the VPN is active (can't load any site). I'm not trying any exotic locations or sites or anything. Quitting the VPN brings internet back to normal. If I activate a different VPN client, using the same country, everything still works. Back to Proton, internet stops working again.

Please polish your product. I really want to use ProtonVPN, but I'm forced to keep using the old one, because it always works, while ProtonVPN constantly has issues.
