@timbray this has been my experience with them as well. Most of the time passkeys just do not work for me.
And I’m a tech nerd deep into the open source computing space, have helped develop cross-desktop standards, and help translate between the nerdiest engineers I’ve met and various levels of less-technical folks. If I can’t get it to work reliably, I don’t think there is hope for most people. 😅
