Slow Typing Speed in Datapoint Due to Missing Hide Transcript Button

Hello everyone, we are experiencing super slow typing speed when typing notes in "Datapoint" under a transcript. We noticed recently that "hide transcript" button disappeared and we vaguely remember that collapsing transcript boosted the speed of "Datapoint" view in the past. When we type something, it takes up to 8 seconds for the text to appear. This is happening on multiple computers and different internet providers.
