My understanding is that this feature is in Premier and Higher versions. Since I am using quicken classic, and my home is not in the USA, how can I turn this off?
Go into Edit Account Details for your House account (Account Type = House) Look for "Use Zestimate by Zillow" and, if there's a checkmark in the box next to it, click to remove the checkmark. Click OK.
Haven't received the popup reminder in a long time, so I'm not sure … In the popup message is there a checkbox with text "Do not remind me" or similar? If so, check or uncheck the box so you don't get another reminder again.
Sorry, misread what the problem was.
