Freezing QuickBooks Online mobile app can be quickly fixed by clearing out excess data stored in your phone's cache, @userricozayas33.
Let's get your mobile app up and running by resetting the QuickBooks Application. This way, you can manage and track your mileage data swiftly. Let me guide how.
For Android:
From More Options, select the Help & Feedback tab.
Choose the Refresh Data menu.
Hit Yes.
For iOs:
Go to the Help menu.
Select Reset App Data.
Click OK.
After that, I'd recommend getting back where you left off to verify if it's already working thoroughly. If the issue keeps going, let's uninstall and reinstall your QuickBooks. Just touch and hold the app, then click Delete. Uninstalling the software won't delete the transactions and subscriptions you have.
Feel free to drop me a line in the comment section if you have an additional question about your app. I'm keen to help. Wishing you the best of day -today.
