Nuclides in the vicinity of ${}^{94}\mathrm{Ag}$ have been studied with the Penning trap mass spectrometer JYFLTRAP at the Ion-Guide Isotope Separator On-Line. The masses of the two-proton-decay daughter ${}^{92}\mathrm{Rh}$ and the beta-decay daughter ${}^{94}\mathrm{Pd}$ of the high-spin isomer in ${}^{94}\mathrm{Ag}$ have been measured, and the masses of ${}^{93}\mathrm{Pd}$ and ${}^{94}\mathrm{Ag}$ have been deduced. When combined with the data from the one-proton- or two-proton-decay experiments, the results lead to contradictory mass excess values for the high-spin isomer in ${}^{94}\mathrm{Ag}$, $-46370(170)$ or $-44970(100)\mathrm{keV}$, corresponding to excitation energies of 6960(400) or 8360(370) keV, respectively.
