Broad parameters for checking so until someone knowledgeable about such matters pipes up, assume we are talking about a minimum of 10 minutes per app (320,000 of 'em) so total man hours 3200000 /60 = > 50K hours so a team of 50 means 1,000 hours each at 10 hours a day means more than three months with no time to meet their girlfriends/boyfriends/whatever. Even 5 minutes per app = a damn long time
By which time they have to start again on all the new/updated apps.
I hope they had an app for that. Or actually I don't care.
But throws into profile the number of people FB, Twitter etc reckon they have to vet posts. Mr. Orange needs a team all to himself.
