Hi there, @SUVCW.
Let me add info about disconnecting Square in QuickBooks Online (QBO).
Disconnecting Square will remove all the to-be-reviewed transactions. The ones that aren't added in the categorized tab.
On top of that, there are reported cases of error on posting square app transactions. It's best that the connection should still be intact since the technical team will need this to troubleshoot the escalation properly.
You might want to categorize download transactions automatically via bank rules. Feel free to read this article: Set up bank rules to categorize online banking transactions in QuickBooks Online.
If you have additional questions about managing your transactions from Square to QBO, free to come back here. I'll be willing to assist you. Keep safe always.
