If I set up my bank in the app it allows me to do everything except connect my account by checking the accounts I want to use. It says "something didn’t work”

Hi there, @beagles-batten-0.

Thanks for taking the time to reach out to the QuickBooks Community. I hope you're having a great day so far. 

To clarify, have you tried connecting the bank in a web browser? If so, did you receive the same error message? You said "by checking the accounts I want to use", are you trying to connect the bank account to more than one account? 

Any additional details you can share would be a great help in providing the right steps for you to get back to business as quickly as possible. 

I'll be sure to keep an eye out for your reply. Don't hesitate to let me know if you have any other questions or concerns. Chat with you soon!
