When click the button component and expand the logic panel,
I cannot see the default start logic(event).
(Not only for buttons, but also any other components the problem occured, too.)
I tried to create new project, log out, hard refresh, and delete cache, but cannot solve the problem.
My enviroment is Window/Chrome 88.0.4324.150.(newest version)
When I use Edge, this problem is solved.
I find same issue in the post, No Event Blocks/Not Able to Add Logic Blocks
