I sent a test zap to the address in your profile: dbdbdb@getalby.com
Is that the address you’re expecting to receive into?
As for sending, that’s entirely dependent on the type of wallet you chose. Are you connecting via NWC?
(If you’re on Signal or TG you can also pop into the nostr:npub1hxfkcs9gvtm49702rmwn2aeuvhkd2w6f0svm4sl84g8glhzx5u9srk5p6t chat which might be a faster way to triage your issue.)
