After about 15 seconds of typing, it keeps stuttering and lagging, and makes it impossible to type, end up having to tap a letter, wait 2-4 seconds, tap another, wait, and so on. Minimising and reopening doesn't work, restarting phone doesn't work, force closing and reopening doesn't work. A 1995 desktop can process typing faster, and I'm on a s20+. Will be switching to another note system
