I'm glad to see you back in the thread, @dkeiner. Let me provide you with additional steps to disconnect your Square app from QuickBooks Online.

I appreciate you following my colleague's instructions, and you are on the right track, dkeiner. Because you can't find the Disconnect button in the menu, choose Settings instead. Locate the Disconnect option on the settings page, then fill out the brief questionnaire. Finally, click Confirm Disconnect to disconnect the app from your company profile.

If you can't still see the Disconnect option, you can refer to this article to manage your settings or disconnect the app: Connect your Square account to QuickBooks Online. You can also keep this article moving forward if you want to review the detailed steps for reconnecting your Square app to QuickBooks Online.
