Hi: what are the specifications around the following to ensure crisp (non-blurry finishes)
- app icon size (what resolution and size do I use to create new icons that I can upload into the Yik Yak template for both iOS and Android)
- I want to change the image on the “sign-in” or “sign-on” page? (what resolution and size do I use to create new “sign-in” or “sign-on” page that I can load into the Yik Yak template for both iOS and Android)
