It has recently been argued that event-by-event fluctuations, choice in initial conditions, and proper calculations of $v_2\{2\}$ are necessary to resolve the long-standing $R_\text{AA}$ to $v_2\{2\}$ puzzle for high $p_T$ identified hadrons [1,2]. Here we investigate the effects of full event-by-event fluctuating hydrodynamic backgrounds on the nuclear suppression factor and flow harmonics of heavy flavor mesons and non-photonic electrons. We obtain an $R_\text{AA}$ for D$^0$ and B$^0$ that is roughly equivalent, in line with recent CMS results, and find similar results for the elliptical flow, triangular flow as well as the multiparticle cumulants in PbPb collisions at both 2.76 TeV and 5.02 TeV. Finally, we propose new experimental observables in the heavy flavor sector that will provide greater insight into consequences of flow fluctuations as well as further constraints on energy loss models.
