When using the Auto Categorize feature from Prayer AI Automation, it's important to check the Prayer Request Entry block's default settings.
Unless you changed it, the Default Category setting is originally set to General.
To allow AI to categorize prayer requests, update the Default Category to a parent category that has Auto Categorize enabled. This ensures the AI organizes requests based on that parent category's subcategories.
For more details on enabling and configuring AI automation for prayer requests, see the Raising Up With Prayer guide.
