Since upgrading to iOS14 QB keeps crashing when I try to add a split (at the point where I enter the account name). Does anyone know how to solve this?

Hello there, mannahill-estate,

Let's try to uninstall and reinstall the QuickBooks Online app. The update to iOS14 might have affected the app's performance.

You can redownload the app from this link: https://quickbooks.intuit.com/au/mobile/.

Please let me know how it goes so I can assist you further.
