you for reaching out to the Community regarding your issue. I do apologize for the late response. Currently you are able to update accounts from the mobile app. You can do so by selecting the account you want to update. From there swipe down to update the account. It should give you a small circle showing the update.
Currently, reconciling can only be done through the Quicken desktop program and is not currently an offered feature in the Quicken Mobile app.However, if you wish to submit an official request for this feature to be added in the future, what you can do is create an idea post and add your vote. This way other users who have the same or a similar request can vote on your idea.Our Development and Product teams frequently use our idea posts in order to improve Quicken and implement new features requested by customers.
