Cannot add new Certificates to Android Device

Using a Pixel 6a, running Android 13. I am trying to install certificates from a private CA I have established on the internal network. I was able to install the root certificate by doing the following: Settings > Security & Privacy > More security settings > Encryption & credentials > Install a certificate From there I am able to select the ca.crt file I had copied from the CA server. I can see this new certificate when I hit "Trusted credentials" under the "User" section. When I try to repeat those exact same steps to add a server specific cert, it's never added as I can't see it under "Trusted credentials". There is no error NOR a confirmation that this certificate was applied successfully. Edit: When I successfully install the CA cert, I get a small tooltip/popup saying it's been installed successfully. When trying to install the non-root certs, I get no confirmation, and am simply returned to the previous UI view.
