The math feature on Bear is very useful to me, but unfortunately I’ve found it to be quite laggy. For example, if you paste the following text into the Bear (macOS) app, it becomes very laggy (taking a while to render + lots of stuttering while scrolling). This isn’t an issue on the web version at all.
