Exporting Photos in Facebook-compatible format

Trying to figure out how to export a 360 photo from VIRB Edit in a format that is Facebook-compatible. FB has a web page all about 360 ( https://facebook360.fb.com/learn/ ) listing the VIRB as one of the supported cameras. But I can't figure out how to get there. The route that seemed obvious to me was exporting from VIRB Edit to Photos, then uploading that JPEG to FB. But apparently it doesn't have the right metadata, because I just get the flattened image on FB. Maybe there's some other export path? Stumped . . .
