Hello! I see you mentioned that Fast VPN is not working properly and actually slowing down your network on your iPhone with iOS 18.5.0. To help you better, can you tell me a bit more? For example:

- Is the VPN connecting but just slow, or does it struggle to connect at all?
- Are you noticing this slowdown with specific servers or all servers you try?
- Is your internet speed before VPN usage usually good?
- Have you tried switching VPN servers or restarting your device?

Sometimes VPN speed drops happen because the VPN server you connect to is overloaded or far away, causing extra network routing time and encryption processing that slows the connection. Let’s go step-by-step to improve your speed:

1. Try a Different Server: On your Fast VPN app, select a different VPN server location that’s geographically closer or less popular. This often reduces server overload issues.
2. Restart Your iPhone: Simple but effective to clear any network glitches.
3. Check Your Internet Speed Without VPN: Use a speed test app or website to see if your base connection is stable.
4. Update the VPN App: Make sure Fast VPN app is updated to the latest version for best performance on iOS 18.5.0.
5. Disable Unnecessary Features: Some VPNs have features like ad blockers or extra encryption that can slow down speeds. Try toggling those off in the app settings if available.
6. Try a Different Protocol: If Fast VPN allows protocol switching (e.g., from OpenVPN to WireGuard), try switching the protocol for potentially better speed.

If none of these help, there could be network-related or account-specific issues causing the slowdown. At that point, I can assist with checking further settings or help you get in touch with our specialist team.

How about we start with testing a different server and checking your base internet speed? Let me know what you find!
