I am using it in Chrome on Windows and macOS and have not seen this behavior. Could you try to create a new Chrome profile (using the profile icon at the right top, add a person, and so on), add LastPass there and see if it still happens? If that keeps working, it might be your usual Chrome profile to be broken. If you use a Google account to sync your data
, you can create a new Chrome profiel and then login again to get your data and settings back.
