Hello, @Jarm.

I can share with you some information about the notifications/recommendations in QuickBooks.

The pop-ups are designed to guide and suggest you on how to improve your QuickBooks Online (QBO) experience. The only way to stop these notifications is to manually close it by clicking the X or No, thanks button.

I understand how seamless it would be to turn off these recommendations from your account. Rest assured our engineers never stop to enhance QuickBooks and deliver the best experiences for all QuickBooks users. To stay current with the latest QuickBooks news and updates, feel free to check out our blog. Here's the link: The QuickBooks Blog.

Once done, you can as well read the topics from our help articles as your references in the future.

I want you to know that I'm always here to help if you have any other QuickBooks concerns. Just add a comment below. Have a good day!
