If you have watched my youtube video about changing wordpress site url and you use elementor, then you will have to follow these extra few steps to update url in elementor. (15 Apr 2021 Update: In most cases you are not required to do these changes.)
Note: Before making any changes make sure you create a backup of your wordpress website.
Login to wordpress dashboard
Go to Elementor > Tools
Go to Replace Url Tab
