Many teams maintain EPUB as the main file and create MOBI only for compatibility with older downstream requirements.
The export is direct, but the review stage matters because MOBI is a more limited format than EPUB and should be tested in the destination environment.
Choose the EPUB from your device. This page only accepts EPUB, so the starting format is fixed from the first step.
