Hi szomaza,
Same as you, I lost a lot of time trying to make things work again...
Now its kind of working... I can see the ads working, what i had to do is to delete and make a new ad game in unity dashboard online, then copy the number of the game inside the unity services tab.
With Jean new actions it works, the play and reward work, but the skip and the others doesn't show anything for me...
(anyway you will see them just when you run on iOS after xcode).
1. the game id goes inside the services tab on unity
2. you don't need to pre cache, unity does that for you
Yes some more documentation on the new playmaker actions would be awesome too!!
basically, once you manage to put your game on the unity network, using services tab and the unity dashboard for ads, the actions start to work.
Besides when there is a problem, this i could not manage to see working on my device or in unity. I can not see my message of no ads, when the ads doesn't show or encounter any problem.
If someone have more info, please share.
Thanks,
Doug.
