Some juristictions do not follow naked eye sighting. There is a vast permisibility within the madahib of what counts as a valid sighting. Arab lands are all using different criteria so you have Egypt saying no moon was sighted and KSA saying it was. Best to follow your local scholars if you are outside the rule of a muslim government. If you are able it is a beautiful experience to sight a new cresent on your own and brings certainty to your soul.
