For the past couple months the Lastpass app will periodically stop accepting the Yubikey generated 2FA code when logging in and when I cancel out of the Yubikey code entry the app offers to remove 2FA (which is an odd Ul prompt for a security minded password manager). I have to clear the app cache every time this happens to get Yubikey integration working again. It would be appreciated if someone at Lastpass could look into this, it's a consistent and reproducible problem across app and android versions.
