Hello there, @electrogump81!

Let me share with you some insights into what's possibly causing your QuickBooks Online app to crash.

Initially, QuickBooks Online uses browser cache and cookies to run faster, but sometimes these can cause issues. Try logging into your account using a private or incognito browser to manage sales tax.

Check for app updates to ensure that you're using the latest version of the QuickBooks Online app. Updates often include bug fixes and improvements that can resolve known issues.

To troubleshoot the QuickBooks Online app shutdown issue, you can perform resetting the app data. This can help resolve issues caused by outdated or corrupted files. This process clears the app's cache without losing any company data. To reset the app data, here's how:

1. Refresh the app by restarting your mobile phone.
2. Check if the issue persists. If it does, proceed to uninstall the QuickBooks Online mobile app.
3. Reinstall the app to potentially resolve the shutdown problem.
