The isospin breaking and radiative decay widths of the positive-paritycharm-strange mesons, $D^{*}_{s0}$ and $D_{s1}$, and their predictedbottom-strange counterparts, $B^{*}_{s0}$ and $B_{s1}$, as hadronic moleculesare revisited. This is necessary, since the $B^{*}_{s0}$ and $B_{s1}$ massesused in Eur. Phys. J. A 50 (2014) 149 were too small, in conflict with theheavy quark flavour symmetry. Furthermore, not all isospin breakingcontributions were considered. We here present a method to restore heavy quarkflavour symmetry, correcting the masses of $B^{*}_{s0}$ and $B_{s1}$, andinclude the complete isospin breaking contributions up to next-to-leadingorder. With this we provide updated hadronic decay widths for all of$D^{*}_{s0}$, $D_{s1}$, $B^{*}_{s0}$ and $B_{s1}$. Results for the partialwidths of the radiative deays of $D_{s0}^*(2317)$ and $D_{s1}(2460)$ are alsorenewed in light of the much more precisely measured $D^{*+}$ width. We findthat $B_s\pi^0$ and $B_s\gamma$ are the preferred channels for searching for$B_{s0}^*$ and $B_{s1}$, respectively.
