you for reaching out to the Community regarding your issue, although I am sorry
to hear that you are experiencing issues with your mobile app. Simplifi is a mobile platform made by Quicken for people who want a cloud based product. That is what Simplifi is but I'm confused are you seeing it every time you open the Quicken app? Are you being asked to download simplifi or what exactly is happening each time.
Once we're able to get more details we'll see what we can do in order to resolve the issue you're having.
Out of the blue, when I tried to access my quicken mobile app, something called "Simplifi" comes up.
