The ads in QuickBooks are designed to guide and suggest you how to optimize your QuickBooks Online experience.
For now, the only way to get rid of the advertisements is by manually closing them through the X sign or the No thanks option. This will prevent the pop-ups from showing up again.
Since they're affecting your navigation, I'm personally taking note of your feedback regarding the popups. Our engineers make improvements in the program by listening to our customers' suggestions and comments.
You may visit our QuickBooks blog site to know more about the latest news and updates about QBO and what our Product Team is working on.
For QuickBooks Desktop, you can follow these steps below to turn it off:
Go to the Edit menu.
Then choose General on the left-side panel.
Click the My Preferences folder.
Check the box next to Turn off popup messages for products and services.
Once done, click OK.
Feel free to reach out to me if you have additional concerns besides these advertisements. You guys take care.
