Hello @shrindhi rao ,

May I know if it is a Basic or Standard SKU load balancer?

If it is Standard load balancer, you can add any virtual machines or virtual machine scale sets in a single virtual network.

If it is Basic load balancer, you can add Virtual machines in a single availability set or virtual machine scale set.

The UI has changed in the portal. All you need to do is to select Virtual Machine and select VMs which you wanted to add (Part of availability set).

If you try to add VM which are part of different availability set, you get an validation error as below:
