We analyse the cross-section of events with Large Rapidity Gaps observed in proton–lead collisions by the CMS Collaboration (arXiv:2301.07630). The role of the transverse size of elementary pN amplitude is discussed. We emphasize that the cross-section of incoming proton dissociation caused by the photon radiated off the lead ion is close to the value of 
measured by the CMS, and it is not clear why there is no room in the data for the Pomeron-induced contribution
