Ideapad 720s 13IKB - Thunderbolt port not working

I have only had this laptop for a month or so,  but the Thunderbolt usb-c port stopped working. I can still use this port to charge my laptop, but it won't connect to any other devices nor output video to an external monitor. Has anyone encountered this problem before? Does it mean I need to send my computer back for a repair? Thanks.

I have the 15 inch version. I had the same problem. Updating the bios worked but now im having the same problem after 3 months of it working properly.

Thanks for the suggestion. I tried updating the bios, but the problem persists still.
