Hi, mark122.
I'd like the chance to get you back up and running with the app. We update our app regularly to improve performance, fix bugs and add new features so that you'll always know where your business stands.
I can pass along all the feedback you have to the appropriate channels so you're able to reach a point of resolution as quickly as possible. For now, I'd encourage you to visit our QuickBooks Blog, so you'll be updated with our latest news and updates including product improvements. Just go to https://quickbooks.intuit.com/blog/.
To get more details about the QuickBooks mobile app, see this article: QuickBooks Mobile: Frequently Asked Question.
If I can be of additional assistance while working with QuickBooks, don't hesitate to let me know. I'd be more than willing to lend you a hand.
