Tried to replicate using the latest Chrome Canary w/ Android version 8.0.0 + Samsung Experience version 9.0 and it doesn't even load the forum index aka /all route lol.
Edit: Wow, Chrome Canary eventually crashed for whatever reason after attempting to load the all discussions view ?
Edit 2: because I don't like double posting, I tried disabling "Safe Browsing" in Chrome Canary's settings and that seemed to have done the trick. I tested it out some more and turned it back on and as soon as I closed the app and attempted to visit discuss.flarum.org, it crashed again.
AXON try disabling "Safe Browsing" and let me know if you can see the emoji's now, I have a feeling that Chrome Canary is blocking the CDN thinking it's harmful to your phone.
