Hello, I'm new here. I'm a children's book designer and have recently started working for Reedsy. I'm having issues exporting to ePub from Indesign (latest version). The resulting file looks great on my iBooks reader but the clients tell me that on the kindle reader the text has boxes around it, psd files overlap and generally everything looks terrible. I've tried asking for advice from KDP but no help at all. Can anyone advise please? Thank so much!
