Thanks, I have dabbled with that in Chrome desktop. I guess I underestimated it due to the interface not looking like much, but maybe the simple method of using an extension to fill the nsec is what is most widely supported right now?

Alby on Firefox mobile was good earlier, but now is proving unfathomable. Also, earlier, I had to copy-paste the nsec to login to Primal, whereas presumably nos2x shielded your nsec for you?
