There is no desktop / mobile different capabilities but OS / browsers versions supporting SHA2 or not.
the following link list minimum version of well known products that support SHA2. https://www.digicert.com/sha-2-compatibility.htm
OTS02Perhaps the intermediate (or chain) certificate does not match the new certificate. When the CA issued the sha2 certificate, did they specify a intermediate certificate that is different from the one in the SSL client profile?
Internet Explorer will usually not give a certificate error in this condition (I think because Windows Updates load all of the major CA intermediate certs). But Firefox and Chrome, etc will give certificate errors. Just a thought.
