Alternate Solution
I found alternate solution. Just remove apps permission on Facebook. Remove Instagram permission on Facebook Account Setting (prefer open with full desktop version). After that, open Sharing Options on Instagram apps and try again connect to Facebook account. =)
To share on facebook or others:
Uninstall fb app first.
Then open instagram, post a picture then tap the share icon on facebook.
After sharing, install fb app.
Its a bug even on official instagram app.
