Hi! Can you please contact us through the ‘Report an issue’ option in the app menu and let us know which servers you’ve tried, what’s your native ISP speed vs. VPN speed (speedtest screenshots would be helpful), so we can document your feedback for future improvement? Thank you in advance.

We’d appreciate it if you could contact us at https://protonvpn.com/support-form and tell us the exact servers you’re using, so our technical support team can assist you accordingly.
