Finally, I was able to claim and see it

It is definitely better to use the posting key to claim it , I would like the same in Keychain, but unfortunately, it asks for the active key. Can't we change that ? I mean use the posting key to see the balance in https://spk.dlux.io/ ? Unless one wants to transfer, why do we need the active key ?

Thank you so much for the detailed guide - it was worth waiting late to see this.
