Actually they are posting flight tracking with cancellations for today and tomorrow. https://www.intercaribbean.com/travel-tools/flight-track.html I'm watching as we are slated for March SJU-EIS flights and hoping they get more up to speed in the next couple months.
No flights were cancelled yesterday, 1/12. The first flight is canceled for today which is not uncommon if the flights aren't full and they can accommodate the passengers on a later flight.
