Hello,
I recently upgraded my iPhone 13 to iOS 18.0, and I've encountered an issue with VPN applications. After downloading and installing the required certificate for the VPN, I noticed that it does not appear in the "Certificate Trust Settings." Because of this, I am unable to mark the certificate as "trusted," which results in the VPN application's features not functioning properly.
This issue is critical for my VPN usage, and it was not present in previous iOS versions. Could you please provide guidance or suggest a solution to this problem?
Thank you for your assistance!
It’s better if you reply as a reply; if you reply in the comments, I may not see it. See Quinn’s Top Ten DevForums Tips for this and more titbits.
It's Quantumult X, a VPN app from a third-party developer.
OK. I can’t really help you with that. DevForums is focused on helping developers use Apple APIs and services. Apple has another site, Apple Support Community, run by Apple Support, for user-level issues. However, in this case my advice would be that you contact the developer directly. They’re in the best position to know about any compatibility issues with iOS 18.
Share and Enjoy
