Thank you for sharing your setup! To clarify and provide the best assistance, could you confirm which specific model you are using for this automation rule? In Odoo, the model selection can impact the behavior, especially if the rule applies to a custom model or a specific Contact model variant.

Additionally, in Odoo 17, automations can be implemented in various ways, such as through direct code modifications or the "Update Record" function in automation settings. If possible, could you also verify whether the domain or conditions for this automation are correctly configured? This can sometimes be the cause of activities not triggering as expected.

Let me know if you can provide these details, and I'd be glad to assist further!
