nostr:npub1w4uswmv6lu9yel005l3qgheysmr7tk9uvwluddznju3nuxalevvs2d0jr5 Might i suggest you to share private keys with qr code, yesterday I enabled amber on my second device, and I had the problem to copy and paste the keys between 2 devices, now we can import keys with qr code but lack the functionality to export.
My two cents
Bye
