App not working on iOS 16.6

[nexdom00]

hello I'm trying to use your app, it builds correctly, transferred on iPhone (iOS 16.6+certificate is ok) but as soon as I try to activate the VPN switch it immediately goes from green to grey. Everything is ok on server side because I already use iodine on other linux and Mac machines. Your help would be very appreciated, thnx in advance p.s if you need further info on my configuration just let me know
