Make sure the game version matches the trainer game version. The trainer recently had 10 reports of people using experimental branch which we dont support.
Apologies. I genuinely didn't think if the experimental would be supported or not. My assumption was that the game was big enough to get the attention for a trainer. My bad for wasting a report.
Gonna go ahead and say ignore my report as well, just looked through here and saw, my bad.
You can clear it by going via the update request button and at the bottom left corner it should be a cancel/clear update request.
