Why can't I transfer my AXS tickets?

I'm curious, why is it that I'm unable to transfer my AXS tickets? I've tried several times but the option seems to be unavailable. Could it be because of some sort of restriction or policy change that I'm not aware of? I would appreciate any clarification on this matter as I'm quite eager to attend the event and want to ensure that I can share my tickets with my friends if needed. Thank you for your time and assistance.
