I'm using Android Studio Bumblebee | 2021.1.1 and I'm having an odd issue when dealing with the Constraint Widget. If I create a new project and open the activity_main.xml layout, then select the default "Hello World" TextView and try and make changes to the top margin or bottom margin values, they don't seem to change. When I click on something else and go back to the TextView the values will revert. I think it's probably a bug but I wanted to see if anyone else was having the same issue?
