Thanks for the response. I'll be integrating it into my app, so the PNG export is a non-negotiable for me. I was thinking of converting the pdf to png, but it doesn't look that good. So i'll have to find another tool until the PNG export is rolled out.
I can't use the API for my use case with only pdf and ppt being options for social posts. Seems like the API was built for presentations only, and not actual social.
