Hello, Empoweredelectrical. I appreciate you taking the time to run through those troubleshooting steps. To break it down for you, Error 00001186 in the QuickBooks Mobile app indicates data sync issues or a corrupted cache related to categorizing transactions.
Since the error continues after the troubleshooting steps, I recommend contacting our QuickBooks Live Support team to further investigate your account and examine the underlying error issue. Just navigate to the Menu page > click the (?) Help icon > select Articles and Support > From there select Contact Us and follow the prompts.
Alternatively, you can categorize your transactions by logging into your account using a mobile browser.
Feel free to leave a comment if you need help with any QuickBooks concerns.
