x.509 Client Certificates not working on SAP Fiori Client 1.5.0 (iOS)

Hi all,

We've successfully configured x.509 client certificates on SAP Gateway and it works fine using Fiori Client 1.5.0 (Android) and desktop browsers but we cannot use this logon procedure on iOS devices. Also we manage to use x.509 client certificate on Safari (iOS) by contrast SAP Fiori Client 1.5.0 app never allows us to select client certificates included in iOS profile.

Any help will be appreciated, thanks in advance!

Emi.
