@nobleapex2022, sorry to hear about the trouble. Neither iOS nor Android media gallery applications (iOS Photos, etc) natively support the 360 media created by Fusion. Therefore, we cannot save content directly to the those applications. Content will be saved in the Local Media section of your GoPro App.
As for the Facebook sharing problem, we've shared the information to the team in charge. We'll keep everyone posted as soon as new information is available.
In the meantime, you may export your video through Fusion Studio on your computer and manually upload the 360 videos onto your Facebook. You can also utilize OverCapture and you should be able to share the clips from the app to Facebook.
