I like the app everything is right but I can't upload content like videos.
that's a downside. please fix it if you can!
The option to upload videos is already available in the app. Please find this option by clicking on 'Custom Content' from left sidebar menu and then click on the blue button located towards top left 'Add new'. Hope this helps :)
If you need any other help with the app, please feel free to let us know.
