Hi @EruptSvgymsj
Can it be used by others within the organization?
Is there an update to the Teams web client?
The sequential approval process was introduced in May 2023. However, the client availability time for this feature is not uniform, and you may have to wait for a while. You can check the Microsoft 365 Roadmap for Teams sequential approval updates.
Here's a roadmap for Teams sequential approval updates: Microsoft 365 Roadmap | Microsoft 365.
