Mobile App can't use installed user certificate

I created my own CA and signed a couple of client certificates for my own devices. I added the CA cert as ssl_peer_certificate in http and installed client certificates in my desktop as well as Android. Both the desktop and Android work fine when using Chrome. However, Mobile App doesn’t seem to know how to use the user certificate installed in the system. It just got rejected by the server without even asking for a certificate. Is this a known issue? Is there any plan to fix/implement it?

I am nervous when exposing my home devices on the internet, even with https. Being able to limit the connections from only trusted clients is a great relief.

currently not supported there is a PR being worked on but not sure what will come of it
