Hi Dan, thanks for the heads up. I have fixed the mobile bug and deployed the update. It should be working for everyone now. I've also replied to the users above.
Thanks for flagging the Firefox Focus issue. I've just pushed a fix for mobile browsers. It should be loading correctly now. Let me know if it works for you!
I put this post in the SCP (https://news.ycombinator.com/item?id=26998308) - will temporarily bury it until the author confirms it's working. Sorry for the inconvenience!
