Hi, after 48 hours, problems appeared in the user interface, such as the disappearance of applications, Cramps in the notifications panel, we need fix soon.
it's normal. did you made a back up before updating? I'm using s10plus, first time my apps some where missing, some are out of folders, some were disabled. my phone was lagging hard, try to switch it off for few minutes, it will be fine. if the problem continues you have to wait until the patch update.
