Update required: your LastPass Mac App is outdated.
hHave installed the latest Mac App and the browser extension (Blue icon on my browser). Nothing happens when trying to open the app to login (from the extension, launchpad or app store). any ideas?

Thank you @jepenny​ for your prompt response.  I have followed the steps in the article, but get blocked at step 6 (On the login screen, enter your email address andmaster password, then selectLog In) as the LastPass login screen does not appear.

In case I was doing something wrong, I uninstalled LastPass and the browser extension and followed the steps again. Unfortunately, I got the same result.
