I'm trying to create my app, but can not get past the Assets tab. Every time I try to upload my PNG files, I'm getting a red exclamation point with an upload failed error. My files are saved as PNG and are the exact dimensions needed. I have tried in both Safari and Firefox. Has anyone else had any issues with this? Any suggestions on how to get past it?
I saved to web from Photoshop as a PNG. I should add that I got it to work from a Windows computer, but still getting errors on the Mac.
