I am not sure if my migration has been done correctly?
Could someone please verify it for me https://btc.com/12AGU6Gtjrm22ygQzgvz6MbiEUnzrzjqo2
Sorry, but you rushed the process and failed to set the second half.
Only one half is set, plus your burn txn.
You need to Reset and go thru steps 1-4 again, but use the block explorer after step 3 to watch for the txn to be confirmed, then return to the wallet and set the second half in Step 4.
After that is done successfully, your previou burn will get registered.
