I am just starting out using Combo as a trial and from a vanilla install I am getting a lot of these deprecated feature errors.
I have checked the page and it does not have anything related to the error that has been added by me. Is this just a php8.1 issue that hasn't been worked out yet or is there something that I need to set up?
Menubar - slot_header - The align attribute has been deprecated, you should delete it or use the container instead
Support - slot_header - The component attribute (container) is unknown or does not apply
