  The isospin breaking and radiative decay widths of the positive-parity
charm-strange mesons, $D^{*}_{s0}$ and $D_{s1}$, and their predicted
bottom-strange counterparts, $B^{*}_{s0}$ and $B_{s1}$, as hadronic molecules
are revisited. This is necessary, since the $B^{*}_{s0}$ and $B_{s1}$ masses
used in Eur. Phys. J. A 50 (2014) 149 were too small, in conflict with the
heavy quark flavour symmetry. Furthermore, not all isospin breaking
contributions were considered. We here present a method to restore heavy quark
flavour symmetry, correcting the masses of $B^{*}_{s0}$ and $B_{s1}$, and
include the complete isospin breaking contributions up to next-to-leading
order. With this we provide updated hadronic decay widths for all of
$D^{*}_{s0}$, $D_{s1}$, $B^{*}_{s0}$ and $B_{s1}$. Results for the partial
widths of the radiative deays of $D_{s0}^*(2317)$ and $D_{s1}(2460)$ are also
renewed in light of the much more precisely measured $D^{*+}$ width. We find
that $B_s\pi^0$ and $B_s\gamma$ are the preferred channels for searching for
$B_{s0}^*$ and $B_{s1}$, respectively.
