Hello everyone. I had the same thing. Just like @AtomicimotA said here, I looked into the AMS buffer unit - which I think is what the unit is called. In my case, I simply removed it from the P1S and let it sort of dangle. I noticed LOTS of dust around the buffer unit SPOT on the P1S. Before I removed it, the AMS seemed to struggle. After I removed the buffer, the AMS returned to normal operation. I ASSUME it was binding a bit with the particulate that maybe it was rubbing against. Thx everyone!
