While developing my app, I uploaded a CSV file to the Media section using the "Upload File" button. However, I can't drag and drop it into the screen or blocks section, which prevents me from accessing the file in the app. I've done this before, but now, whenever I try to drag the file, the right-click menu appears instead. I tested this on both Chrome and Edge. I'm using a laptop trackpad since I didn't bring my mouse to my remote location. The trackpad works fine for dragging files in Windows Explorer. Also, I'm using App Inventor after nearly a year. When I try to drag the file to the main screen, it goes to the right-click menu instead of the Non-Visible section.
I have no such issue. Did you try 'Classic' UI?
Same issue in classic UI as well

I have never been able to do this. You usually address media folder files via a component that handles them.
Very long back, I was using File component in Storage section, now its not there
