Categorising new transactions

Hello there, Marleen. Error 00001186 in the QuickBooks Mobile app indicates a data sync conflict or a corrupted cache during transaction categorization.

Since the error continues after reinstalling the app, I recommend contacting our QuickBooks Live Support team. They can take a deeper look into your account and help resolve the underlying issue. Just navigate to the Menu page > click the (?) Help icon > select Articles and Support > From there select Contact Us and follow the prompts.

In the meantime, a quick workaround is to use your mobile browser. Just head to qbo.intuit.com and log in there to categorize your transactions as usual.

If you have any further questions, please feel free to reply below.
