Uploaded images on sheet are showing blurry

Hi there,

I've created a sheet and have been uploading images from my phone via the app. All images look very sharp on the phone even when zoomed in. However, when I open the same sheet on my desktop all the images appear blurry and they export blurry too.

I can't seem to locate any settings to adjust this. I've tried different browsers / computers and still have the same result.
