Prime Infrastructure 3.4 - Wired Clients not populating

All of our switches are talking via SNMP v2c to Prime. 3750 switches are sending wired client info Prime that is populated in device details of each switch. All newer switches (3850, 9300, 9500) are not populating. Sounds like it is an SNMP context that may be missing. When checking SNMP groups, it looks identical on a 3750 compared to a 3850 (only thing different is storage-type (non-volatile vs permanent (Assume Cisco renamed non-volatile to permanent).

I found a forum that referenced having to add context to the group. When I tried this, it created another group instead of modifying the existing group leaving off the existing ACL.

Any idea if that is what is missing to allow Prime to see the wired clients? If so, what do I need to do to allow all VLANs report wired clients to Prime for an existing group?

snmp-server group <whateveryourgroup> v2c context vlan- match prefix 

Thanks
