Good afternoon, @howdy2.
Hey newcomer! Allow me to point you in the right direction to connect your Square app to QuickBooks Online.
To clarify, have you tried all of the following actions to help resolve this:
- Trying a different browser
- Sign out then back in
If the issue persists after doing these steps, I recommend contacting our Customer Support Team for further assistance. Here's how:
- Go to the Help icon in the top right-hand corner.
- Press the Contact Us button.
- Give brief description of the issue and hit Let's talk.
- Scroll down and choose to Get a callback.
Keep us updated on how it goes. I'm only a post away if you need me again. Take care!
