Those certificates are user-added certificates, not system certificates. Android has two separate certificate stores, the UI only exposes the user certificate store, and by default apps only trust the system certificate store. This was changed back in 2016, the original announcement post has some good details: https://android-developers.googleblog.com/2016/07/changes-to-trusted-certificate.html https://android-developers.googleblog.com/2016/07/changes-to... Enterprises can add certificates to the system store I believe, but only as part of the initial provisioning of the device, and only for enterprise-managed devices.
