Hi Ernest,
As usual your support has been excellent. Fixing issue #1 has been a saviour!
I think there is still a persistent issue with #2, as after multiple cache clears and devices I am inconstantly seeing the wrong font. Seems to be on desktop rather than mobile, in Chrome.
Not sure if you had any other ideas, however regardless I plan on doing a large update to plugins / theme etc next week, and can report back if it is resolved.
