When you add a RichText TextLabel, and use the markdown for the “Mark” prorperty, it doesn’t do anything in Studio or in-game.
<mark color="#099660" transparency="0">hi</mark>
Expected behavior
The TextLabel should look similar to the example on the Docs (Rich text markup | Documentation - Roblox Creator Hub)
Thanks for the bug report - this is currently expected. The mark rich-text tag is not yet enabled because client version 658 (the minimum required for the mark tag) has not yet fully rolled out.
Oh alright, thanks! Didn’t work in Studio either - looking forward to the release!
