Hi guys!)
Any help or guidance really appreciated

Thank you for your work on the plugin, it helped me to achieve good results in voice transmission in my app.
But 2-3 weeks ago something gone wrong and I cant find right answers. I would say something mysterious!!!))
You could ask why I'm writing here? Because issue is represented just on IOS platform, where I use your plugin and google is not giving me any answers on my questions))))
I suppose that somebody could face same issues.

Maybe somebody had something similar and could guide me where to look for solution

Data

Voice transmission ionic-cordova app
Latest rtcmulticonnection library is used on client and server side
cordova-plugin-rtc for ios platform
Packages versions I'm using
"cordova": "^10.0.0",
"cordova-ios": "^6.2.0",
"cordova-plugin-iosrtc": "^6.0.2"

Problem
Everything worked fine, for at least 6 month. And I haven't changed anything, nor on front or back side of app.
But lately, 2-3 weeks ago audio transmision between Android - to IOS, IOS - IOS had broken.
Android - Android still works fine.
As I know, with the latest IOS update apple provided some security changes, so it could be related to that changes.

Additional data
No errors on the server side, tried older plugin versions

Here is the error I'm recieving:
