Hello there, @JeremyP2.
In QuickBooks Online (QBO), the ads are designed to guide and suggest how to optimize your QBO experience. I see how the ads affect your navigation. However, we're unable to completely remove these pop-ups.
We can click the X icon or the No thanks button to close the ads. Doing that several times would make the system recognize that it's unwanted on your part.
I'd recommend visiting our QuickBooks Blog to stay current with our latest features and product updates in QBO.
Also, check our Help articles page to learn and read some great resources for future reference.
You can always leave a query to this post for further assistance. I'm here to help. Have a good one.
