iPhone XR 13 - Installed root certificate is not listed in "Certificate Trust Settings"

Dear all,

I've generated a 2048 bit certificate via to use B1if to connect iPhone to SAP B1 via SAP B1 Mobile app.

On several iPhone I installed and enabled the certificate without problems.

Now, on an iPhone XR 13 the installed root certificate is not listed in "Certificate Trust Settings".

Is it an iOS bugs? How can I solve this issue?

Best Regards

Emanuele
