I have just attempted to fill an order by importing from Etsy to print shrimp but it did not import. I have connected to Etsy via PS integration when setting up my shop. I’ve had to manually import and then add address and pay for order myself. Any help with this welcome?

Has anyone used Photopea to upscale images for printing? I’ve been creating artwork using Midjourney and upscaled using creative, but I understand that the image resolution is only really suitable for printing up to around A3 size — is that right? I’m looking to produce some A2 prints and was wondering if anyone has used Photopea (or any other tool) to upscale their images while maintaining good print quality. Any tips or recommended settings would be really appreciated!
