I agree, plus locked Notes cannot include attachments. @ShermanWilcox here turned me on to the app Uplock, which has versions for Mac, iOS, and iPadOS, syncs with iCloud, and can import from 1Password. So far for me it’s a great substitute, and cheaper than a subscription to 1P if I remember right.
