Italics on Kindle app for Android

Hi,

My ebook was formatted with css/html, and converted with Calibre. The italics show up in the Kindle app for PC, as well as Kindle Fire and legacy Kindle devices. They do not show up in the Kindle app for Android. The app is up to date.

I've tried html italics tag, em, and css id but all with the same results. I specified the font as Times New Roman. Same issue.

Any ideas?

Thanks,

R
