I have installed the LastPass Authenticator on my android 8.0 device and also enabled 2FA for my lastPass account. When I try to log in to the LastPass website, I enter my username and password and then it asks for the one-time password. At the same time, the Authenticator app shows a notification that allows me to approve the login. If I click the Approve button, it will always fail with an Authentication error (Authentication failed) The code itself is valid though, because I can enter the code manually and then the login does succeed.
Why does the LastPass Authenticator app not work in combination with my LastPass account?
