Can't upload an image to Polypad

I am trying to use the upload image button on Polypad in the activity builder and it will not work. I click on the button, it opens my file explored and will allow me to select an image. But once I select it nothing happens. I have tried switching browsers, switching images, and trying different file extensions and nothing works. Is this a common problem?

Bumping this up to a bug status

Hi Anthony. Dave from the Polypad team here. Thanks for the report. While we work out the bug, you can upload images to a Polypad in Activity Builder using drag-and-drop. So, you have the image on your desktop, you can just drag it into the Polypad.

Thank you so much, I tried the click and drag and it works!
