Our apologies for any confusion schmeggy929,
In reference to reaching out to the developers that is not recommend for the applications you're attempting to mirror, but rather the mirror software you're using on the PC. The developers of that software would be able to provide the best support regarding the issue you're facing with mirroring.
As outlined in the previously linked article. Apple's available option to mirror is using AirPlay. AirPlay supports mirroring from an iPhone to an Apple TV or Smart TV. Apple does appreciate all feedback regarding their products, services, and features. If you would like to provide feedback about mirroring to a PC you can do so via the Product Feedback website.
Use AirPlay to stream video or mirror the screen of your iPhone, iPad, or iPod touch - Apple Support
Thank you for using Apple Support Communities, have a great day.
