MeduzaVPN runs on a dedicated server with its own IP address. You choose the country you connect through, and if one protocol does not work on a particular network, you switch to another.
MeduzaVPN is not available in every regional App Store. If you cannot find the app in yours, you can change the country or region of your Apple Account.
Settings → your name → Media & Purchases → Country/Region → choose a new country or region.
