I’ve created a topic earlier (Allow users to set Prime Time shortcut to an appropriate value for their country/area).
Not to beat a dead horse, but who exactly are you targeting for the time frame selected? It’s certainly not anyone living in the United States. I’m not saying that the United States is the largest group of Plex users, but I am curious as to who, as you state, that this time frame is targeted for. Please let us know who this group is.
