Since this game was recently updated a few days ago, the trainer will also be in need of an update.
This link will explain the lack of an update request button on the trainer: Why can’t I request an update for a game? - WeMod Support.
Please be patient and wait for the trainer developer to get around to it. Bear in mind this is not the only game they have made a trainer for.
Also - there is no point rushing the trainer update, because hotfixes normally follow major game updates which will break the updated trainer again so soon after it is released.
This thread will be locked due to people posting the same thing over and over without reading previous posts. It will be unlocked again by staff once a trainer update is released.
