How do I opt-out from receiving notification about features and event?
You can turn off in-app product announcement pop-up notifications in your personal settings. You will still be able to access all product announcements by navigating to Support (?) —> What’s New — so you can explore new functionality and training opportunities at your convenience.
To change your personal product announcement preferences, navigate to Settings --> Personal --> Profile and toggle the Show announcements setting in the Product Announcements section.
