This article helps Webgility Desktop users resolve freezing, lag, or unresponsiveness when using QuickBooks Desktop alongside Webgility Desktop. It guides users through cleaning outdated logs, updating software, and properly reauthorizing the QuickBooks Desktop integration to restore optimal performance.

🔍 Common Causes of Freezing
