I can't share posts to Facebook.
Some Android phones, like the HTC EVO 4G and the HC Panache, have known connection problems with Facebook. Keep in mind that the Facebook login process through Instagram is controlled by Facebook.
If you're having trouble logging into Facebook in order to share your Instagram posts, it's possible that Facebook is having temporary issues. Try to log in again after a few hours. Learn more about other first steps you can take when you're experiencing an issue.
For ongoing connection issues, try:
- Deleting both the Instagram and Facebook apps
- Removing Instagram permissions from your Facebook privacy settings
- Re-downloading both apps and attempting to connect to Facebook again through Instagram
