Great app but files won’t upload to Merch – WordRabbit Edit & Add Text Review

I love the interface. It’s pretty easy to make a simple T-shirt. Three stars off because even though it was a great T-shirt design app, when I went to upload it to Merch the file was rejected because it was not a PNG file. Will adjust accordingly if/when this is fixed or explained.
