Anyone also having issue with the screen sensitivity become poor. I having this issue and I write to the team in Facebook. The team called me yesterday and explained to me it is because the CPU will running low when charging (But I believe this is only happens in exynos version). It is to protect the battery but I dont think this is a valid reason. I asked him is all the note 20 ultra has this issue, he said yes and told me "You know right, can't use phone when it is charging"... what a good reason... They should promote this feature in their advertisement. "You will unable to use your phone when you are charging, this is for user safety."
