I see this thread was opened in 2020. The sentiment of everyone who has replied is the same: i.e. not being able to turn off suggestions is simply unacceptable.

Since it is now 2023, and I'm STILL constantly interrupted by USELESS tips and suggestions, it's clear that Quickbooks is uninterested in responding to the needs of their users. Maybe they could care less as long as we pay our fees. Believe me, I'm now on the hunt for an option I can move to that doesn't force me to waste my time with confusing and useless pop-ups.

Give us a way to turn off the bloody things and get your heads out of your other ends, for cripes sake. Why do you want to treat us all like we have no idea how to do our jobs?
