I am having an issue publishing something in Powerpoint 365 using Articulate Studio 360 (desktop app). It will publish, but will not allow me to choose a format, as it does in Powerpoint 2016. I am required to use HTML 5, but there is no option to choose that. What am I supposed to do? How am I supposed to get to the formats that are/were located in the Properties section when trying to publish an item?
