I understand your frustration regarding the lack of API 121 support in Vector. To enhance your experience, it would be beneficial to have a comprehensive API 121 integration that allows for seamless interaction with the system. This could involve developing new features or updating existing ones to ensure compatibility with API 121. Such an update would not only improve user satisfaction but also provide a more efficient and user-friendly interface. It would be great if the development team could prioritize this feature to make the Vector experience more pleasant and productive for all users.
