Narrative:

Received a call from assistant chief pilot saying that my aircraft and multiple others sustained flap track damage coming into ZZZ due to ice contamination. First officer (first officer) was flying and I was monitoring any ice on the aircraft and none was visible. We broke out of clouds at 1;000 AGL and looked back and noticed no ice on the wings but I still reached up and hit the wing anti-ice for good measure for landing and noticed nothing shed from the wings. We landed normally and proceeded to the gate. It seems odd to me that seven aircraft in a 30 minute period incurred track damage and seven experienced crews probably observed the same as I did.
