ANSWERED - MABs - Backup Hyper-V Replica - MABS Can't see replica VM to Protect

(Update: After some time and a REFRESH the replica VM showed in the list)
On:
MABS Server v3 installed on Windows Server 2016MABS / DPM Version: 13.0.415.0 (as shown in MABs Console > Help > About Data Protection Manager And About "i" icon in MABS.

Per this document:
https://docs.microsoft.com/en-us/azure/backup/back-up-hyper-v-virtual-machines-mabs#back-up-replica-virtual-machines

I want to backup a Hyper-V replica virtual machine.

DPM (MABs) doesn't see the replica VM when trying to add it to a protection group. I do see the primary VM (and is available to backup), I don't see the replica VM in the picker. The VM has a healthy replication status.  What am I missing, how do I backup a replica VM?

Thanks,
Dan
