Different balances across Main & Terra 2.0 networks?

Please can someone advise me on the following:
Why I am seeing different Luna balances across the main and Terra2.0 networks? (More on Terra 2.0) Also why my UST is not visible on either network((( and my ANC coins are not visible on the classic network?
Finally is the anchor protocol still practical in its function or is it just a ghost of Terra Past?

Thanks for your help!

I am not sure I understand the issue between “Terra 2.0” and “the main”. Those are the same.
If you want to see the Classic information, you have to select Classic when choosing a network.

Finally is the anchor protocol still practical in its function or is it just a ghost of Terra Past?

Wait for an official annoucement.

Another question : in my classic wallet I have luna valued displayed in ust but when I want to swap that luna for ust the value drops by a substantial X amount?
