Reinstall the app, then everthing should work.
I faced similar problems other reviews did. My solution was to reinstall the app, and then everything worked on my mac, just like good ol days.
I’m not sure it’s VOX’s problem or Apple’s problem, for many Apple apps couldn’t be verified by Apple recently, and the solution was to reinstall those apps.
Just my two cents.
