I’ve been using Lockbox for a few months now on iOS and it’s extremely handy.
When I first installed it I set up autofill just like it says in the app, and it worked fine. When I opened a site in Safari, it suggested the correct login for that site. However, after a few days it stopped suggesting the correct site. It just set ‘Passwords’ and if I click that, Lockbox opens, and there I need to manually do a search for the correct site. Then the login/password is correctly filled in in Safari, so at least that still works, but it was much easier when autofill would just automatically pick the site already.
I tried reconfiguring the autofill settings, but that didn’t make a difference. I’ve uninstalled Lockbox and reinstalled it, and then autofill worked correctly again, but only for a day or two, after that it’s back to just showing me the list of all my passwords where I have to choose the correct one.
I just tried this, and yes, this works! It’s now suggesting the correct login again for any site that I visit.
I tried this last time, before I posted here, and this didn’t work. I haven’t tried it this time of course, since your first suggestion fixed it again for now.
I hope it keeps working now. If it stops again I will update this post and let you know!
