Thank you so much.

Hi There,

Thanks for flagging this - this looks like a bug, we will look into this now. For now, open your experiment settings and in the ‘Use Version’ select 2020.2.6.

Dear Becca,

Got it.

Thanks.

Chen

Looks like it’s not liking the font, could be an issue with what fonts are available on Mac. Forms are currently hard-coded to be in Arial, so it’s possible it’s not finding Arial locally on your machine. I’ll look into this, though I’m hoping to add more customisability to Forms for the next major release!

Dear Parsons,

Thanks for your reply. Now I know what the problem is. I am looking forward to your further information and hoping to more customizability to Form too.

Regards,

Chen
