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

1P_Dave thanks for getting back to me. This is not a convincing answer.
Let me put myself in your shoe: Right after my team created a bug in iOS client, there’s a flourish of users coming into the forum and complaining about keying in the correct details but getting “Maybe there’s a typo?” error. What would be the most likely case, and what would be the fastest way to provide a solution?
Now, if I do not, in fact, know about the issue, that means there’s an internal comm breakdown in your support team. Your knowledge base is not up to date, and it causes unnecessary handover to the email support channel.
OR, forgive me for speculating with suspicious eye, you know about the bug all along, but you do not want others to know that adding a security key to the account immediately breaks the iOS client, and new clients are not able to log in. If you feel like this issue undermines the security of your software, solve it instead of hiding it. If anything this is the key takeaway from the LastPass incident,
