I just finished migration to new #getalby wallet in browser extension, but it was not smooth.
nostr:npub1getal6ykt05fsz5nqu4uld09nfj3y3qxmv8crys4aeut53unfvlqr80nfm I did follow your guide:
well, at this moment you have TWO steps 3 and 5 :-)
Step 3 was ok but I did not realize that all keys are generated. In following step 4 "Transfer Keys:" I was not able to import master key to new wallet until I did "remove master key" in danger zone. I think that you could add NOTE about "removing just generated keys before importing those from old wallet" in step 4.
anyway, thank you for very much your service
