Apologies for using this thread as a support thread, but I got good answers here before so may as well keep trying.

Is the attached wallet functionality dependent on the device you're on?

I got a different UX while logged onto SN from my phone than my desktop. I set up attached wallets with Alby/NWC from my desktop, and after a bit of jerry-rigging, it all worked fine. I can zap and it will automatically send using my Alby Wallet. I can get zapped and I will automatically receive it into my Alby wallet.

However, when I try to zap from my phone, a lightning invoice appears, which is different behavior from the desktop.

Both devices are accessing SN from Chromium.
