No IPv6 on ChromeOS

When using Cloudflare Warp on any ChromeOS device (Chromebook in my case), IPv6 connectivity stops working when WARP is enabled. A very strange issue, since my network and ChromeOS device does fully support IPv6 when WARP is turned off. I’ve tried using other ChromeOS devices with WARP, and they’re having the same issue.

WARP turned off

WARP turned on

How do I solve this issue? I’ve already sent a bug report regarding this issue last year, but I still haven’t heard anything back and the issue is still persistent.
Thanks in advance for your help!
