Almost every app in existence (on Android anyway) when you drag the page down and reach the top of the content, it refreshes the page. For those of us with update ADHD, it's habitual.
Not ClickUp! Scrolling to the top opens a search screen... For some reason...
This is counter-intuitive, and creates a hassle as you figure out how to close that search screen.
Keep it simple, the search bar is right there. I can access it just fine if I need it.
