However, I have tried to inject it into our functions.php but it is not working, most likely because we are editing the infos on a profile level, e.g. /submit-listing/profile/
sorry maybe I have communicated clearly enough. We have those things setup on a vendor level and not on a listing level, so the code snippet needs to be adjusted most likely. I have tried to find the respective form-model, but was unsuccessful in doing so.
Sorry for the late reply. The code snippets seem to be ok, please try setting a lower priority for the second snippet (via a comma after the function), e.g. 100000.
