Problem with certificate install on Android 6

Hi all,

When I try to install the SSL certificate on my Nexus 5x, in order to access SAP via SAP Business One mobile, I always get the error "No certificate to install" when I try to install it.

Up to 1 month, I was able to do it without any problem.

I believe this may be linked to any Android 6 update.

My Nexus is configured with authentication method type "pattern", in order to allow to install certificates.

Is anybody experiencing this problem?

Is there any solution to solve this?

Regards,

Manuel Dias
