How do I disable High Definition viewing after I enable it?

Question when viewing photos on iPad Air using the WD mycloud app. Once you click the HD button on the upper right corner of the screen how do you put it back to the standard definition. You would think you would just press it again and that doesn’t seem to work. It’s seems like once you change it high definition you can’t change it back to the standard and it takes a bit longer for the photo to come up which is annoying.

Hello Homer82, welcome to the Community. If you click on the HD button the app will download the full res photo to your iPad internal memory. If you want to delete all of the HD pictures in the internal memory just click on settings and then “Clear Cache”.
