I have tried to upload a photo of my logo to customize the receipt in the Shopify app. The problem is that the size required is 400 x 200 pixels. Why does the app not automatically resize the photos? There is no way for me to upload a picture from the camera roll of an iPad. The formatting is always the wrong size no matter what I do, and I can't access settings from the back office because Shopify has not added POS to the back office. The back office is only for the ecommerce which needs to change. I have a huge problem with this because the iPad app is lacking the full features I am accustomed to accessing on a computer. Without being able to upload the photo file from the back office where sizes can be controlled I will not be able to customize the receipt. Is there any way around this?
