I'll make sure you'll be able to refresh your app on iPhone, alltranhose. 

Let's reset your app's data to isolate this concern for possible data damage. This can be done on the app or on your phone settings. I'll show you how:

• For QuickBooks Online app:
  
  • Android - Select the menu at the top right and choose Settings. Then select Refresh Data and choose Yes.
  • iOS - Select the menu at the top right and then choose Help & Feedback. Then select Refresh Data and Refresh.
    
• In your Phone Settings:
  • Android - From your phone's settings, select Apps (varies by device). Choose the QuickBooks app from the list and select Storage. Select clear data.
  • iOS - From your phone's settings, select Settings, then, click on General and choose iPhone Storage. Select an app that's taking up a lot of space. To free up the storage without deleting the documents and data for the app, select Offload App.
