Problems with LastPass since my upgrade.

I upgraded to Tahoe 26.3 from Sequoia and now my LastPass is not working properly. I have a macbook air. When I go to a site that previously would autofill with my user name and password, it does not autofill. In some instances, when I add the information, LastPass asks if I want to save the information as if it did not exist before. I did check settings and autofill is selected. The upgrade is the only thing that changed, so maybe that is the problem?
