Has IFTTT changed how they handle SMS text messages?

I have a very simple program running on a Photon, with a sensor and a relay board to control and monitor a motorized garage door. I used to be able to operate the garage door and monitor its position by sending commands as SMS text messages, but it’s not working anymore. I haven’t changed my code or the IFTTT recipes, so I’m wondering what might have changed. I do get IFTTT notifications when the door has been operated, so I know the Photon is working and sensors are working, and I have cloud connectivity and correct authentication. Any ideas?

Try checking with IFTTT, since Particle has no influence on how they run their platform :sweat_smile:?

Thanks. I was hoping someone here has had the same problem AND has figured out what the problem is.
