Can't sign in on iOS app - "We weren't able to sign in to your account. Maybe there's a typo?" error

Hello @ziemowit! 👋

I'm sorry that you're unable to add your account to the 1Password app on your iPhone. Please send an email to support+forum@1Password.com with a link to this thread so that our support team can take a look and advise further. After emailing in, you'll receive a reply from BitBot, our friendly robot assistant with a Support ID that looks something like [#ABC-12345-678]. Post that here, and I'll be able to locate your message and make sure it's gotten to the right place. 🙂
