All of my P1 Motion Sensors stopped triggering Alexa routines last night

I have four P1 Motion Sensors in my home that are supposed to trigger an Alexa routine that turns on/off the associated lights. This had been working perfectly until some point last night where they all seemed to have stopped working, and I'm unsure what could be causing the issue. I tried disabling and re-installing the Aqara skill in the Alexa app, but that unfortunately didn't fix it.

In the Aqara app, I confirmed that my motion is being sensed, but for some reason that information doesn't seem to be getting sent to Amazon so the routine doesn't ever run.

Note that this is happening both for turning on and off the lights, which is surprising since I would have expected the routine to turn off the lights to still work (since those should trigger if no motion is sensed).

Any help would be very much appreciated!
