There is this note at the top which is seen on the V2ray configuration page. It isn’t there for formality. Many of you ignore it and then complain about your V2ray configs not working. I get it that many of you are used to the configuration UI on Android that does most of the heavy lifting for you under the hood but you should get used to working with the real V2ray JSON configuration itself. The generation UI is a limited technology in most cases and that’s the reason for this approach in the iOS app. Please follow the message.
If you're not conversant with the V2ray json config format, you can instead just import the v2ray config uri, this way, the app generates for you a compliant json config from that.
