There were changes made to Quick Base between the dates of October 24th - 27th which may affect your add-on tools. Please contact us directly if you experience this issue, we have a solution that will quickly restore functionality.
I can't say enough positive things about the entire team at Data Collaborative. They are smart. They are responsive. And they know Quickbase backwards and forwards. In over 5-years of working with them (often), I've yet to present a scenario they don't have a solution for.
