Yeah, I'm having the same issue as others who are here in November 2020 (the day after the release). Definitely regretting updating entirely now because trying to teach all from one small monitor (when both me and my students are used to me having two monitors) is ruining my lessons. Is there any fix out there or any possibility of this being fixed before the weekend is over and classes resume on Monday? The is extremely frustrating because one would think this kind of issue would be caught in their "extensive" beta process.
