Does each day's challenge come out at a certain time in your local timezone? I have a friend who is seeing day 9 when I can only see day 8. I'd request having new daily maps come out at a consistent global time for the purpose of competing with friends who live in different timezones.
If I'm reading the requirements around being a "browser engine steward" correctly, does this mean essentially only Google and Mozilla can ever qualify for the "Embedded Browser Engine Entitlement"? Even Microsoft seems to be ruled out, give that Edge's engine is based on Blink. Any other smaller browser engines would be ruled out by the baseline web functionality requirements.
For me, it doesn't work entirely in Librewolf 142 (shows the text, and some tags moving around an otherwise black screen), but does work in Firefox Nightly.
