I had an issue with iOS safari where the game variations weren’t being presented as a link/clickable object anymore but just as text.
For better or worse, clearing my cache and logging back in worked to resolve it.
It’s somewhat annoying when that solves the issue, because potentially erasing your ogs per device settings/preferences to solve an issue is a bit of sledgehammer.
It temporarily fixed another issue with stone colours until it was resolved properly
If it’s a cache issue, being able to reproduce what causes this to happen, it’d be great to fix it at the source like with the stone colour issue 
If not and it’s a browser issue, well that’s good to know too for other users
