Hello @PaulS2859 ,
If you're referring to the alerts on webinars or newly released products and updated features / quality-of-life improvements we occasionally display when initially logging into an account, you can click the top-right X for those. This will log in your browser a cookie indicating that you're not interested and do not want to see it again.
If you're using incognito/private browsing, or accessing the site in another way that prevents or clears cookies, it will likely erase and prevent the ability for the site to recognize that you have no interest in whatever was alerted. If you're continually seeing the same alert after explicitly clicking the X in the top-right corner of it, then it'd mean you're using one of these cookie-erasing/preventing programs.
