Mobile app not working on iPhone or iPad. VERY slow. I've uninstalled and reinstalled.

I understand how essential it is for your team to use the app efficiently in the field, Bexg. I'm here to help you resolve this. 

You can refresh your app's data to resolve glitches and enhance the application's overall performance, much like clearing the cache in a web browser. Follow the steps below:

If you're using an iOS:

1. Go to Menu ☰ and tap Help & Feedback.
2. Tap Refresh Data.
3. Click Refresh to confirm.

For Android users:

1. Go to Menu ☰, then select More Options ⋮.
2. Tap Settings, and click Refresh Data.
3. Tap YES to confirm.

If the refresh did not resolve the issue, I recommend uninstalling and reinstalling the application. Otherwise, I recommend contacting our support team to double-check the root cause.

In the meantime, you can access QuickBooks Online (QBO) through your web browser.
