Additional context
Currently, the Syrian Pound (SYP) is missing from the default list of supported currencies in Invoice Ninja. I was advised by the support team on the official forum to open this issue here to track the request.

Please add the Syrian Pound (SYP) to the default currencies database table so it can be selected natively from the settings.
Currency Details for Database:
