I'm having this problem when I log in to Snapie through my phone's browser, where I can add and use extensions. Keychain doesn't give me the option to confirm the login, and I've tried everything. I ended up having to use the Keychain app's built-in browser. 🥴
That's working as designed. On phones, apps can't talk with each other.
This problem I mentioned WAS only on desktop, not on mobile (or at least not for me).
I understand... Yes, I spoke with the Snapie developers and they explained that it can now only be used from within the Keychain app itself. But anyway, that method you show here is interesting to know.
