FB comments import issues

SNAP version: 4.1.1

1. Auto-import is not working at all. Settings are:

2. Manual import is working, but not all comments are impoted. If post have imported comments, and i try to import a new one, SNAP tell me whtat “1 comment imported”, but it nor appears in post and in admin comments list.

3. The “Close” on import pop-up dialogue is not working

4. Om mobile: tap on “Options” link – infinity spinner spin and… that’s all.

Screenshot and error log in browser console:
