Hello alex-burns-lydiu,

Welcome to Community! QuickBooks Online provides various ads to create awareness of features.  Although there currently isn't a way to stop the ads, I suggest selecting No thanks, or hit the X (close) option.  Please feel free to submit your feedback to our Development Team, if you would like to see the option to turn this off moving forward.

If you have any other questions, feel free to reach back out.  We would be happy to help!
