❌ 間違い: Trusting the green switch and skipping any real test.
✅ 右: Compare your IP address before and after you connect each month.
Mistake #3: Leaving the app on a distant server
❌ 間違い: Staying on a random server and blaming the VPN for slow web pages.
✅ 右: Switch to a close server unless you need a specific country.
