The suppression of bottomonia in ultrarelativistic heavy-ion collisions is a\nsmoking gun for the production of a strongly interacting final state in\nultrarelativistic heavy-ion collisions. Furthermore, these final state\ninteractions are consistent with the production of a hot hydrodynamically\nexpanding quark-gluon plasma with initial temperatures on the order of 600-700\nMeV at LHC collision energies. Models which incorporate plasma screening and\nbound-state breakup based on high-temperature quantum chromodynamics are in\ngood agreement with the centrality, transverse-momentum, and rapidity\ndependence of the suppression seen in the highest energy LHC Pb-Pb collisions.\nThe models of heavy-quark bound state breakup/formation are coupled to the soft\ndynamics of the quark-gluon plasma using 3+1d relativistic anisotropic\nhydrodynamics. At later times, excited state feed-down is taken into account\nusing independently constrained excited state feed down fractions. Comparisons\nwith LHC experimental data are consistent with primordial suppression of all\nbottomonium states, with states having the lowest binding energies being the\nones which suffer the most suppression. In this proceedings contribution, I\nwill review recent work to (a) include the effects of regeneration on\nbottomonium production and (b) to assess the effects of a rapidly changing\nin-medium potential on bottomonium production in the quark-gluon plasma.\n
