I was having problems logging in with the nsec.app. It was also on mobile though. I’ll try again on my laptop.

Gotcha. I use a browser extension for signing into web apps. NIP-07 signing is still more reliable than NIP-46.

@The Bullish ₿itcoiner, I just tried logging into Longform.space using Amber via NIP-46 connection string and it didn't work for me either. There may be something wonky with how Longform._ is handling NIP-46 signing.
