When precheck first started, got the three beeps and used precheck almost every flight.

Since the past few months, I am not getting he three beeps at all. Removed my known traveler Id from my United profile, few a few more flights, but same problem.

Added the number back and still no luck.

Tsa site always mentioned something about US citizens are eligible, but since it wormed before and I have GE, would think it would work,

Anyone else have e same issue or have a green card and GE and precheck accepting?
