Thanks for the lightning fast answer. So, yeah, before buying prime[31] plugin, I tried the native solutions first, but nothing was working.
For example, I've downloaded your example before. In any case, I've downloaded it again now just to be sure, but the following steps occur when I open the project.
1. The project opens just fine, compiles just fine. The build works great, but the rewarded button refuses to show me anything. At least it SEEMS to be working.
2. But when I close the project, I am prompted with the following choice:
....... "Remove or replace play-services-ads version 8.4.0 with version 9.0.2?" and two buttons, "OK" and "Keep".
....... No matter if I choose Ok or Keep, I am prompted with another window
....... "Remove or replace play-services-basement version 8.4.0 with version 9.0.2?" and two buttons, "OK" and "Keep".
3. No matter if I choose both "ok" or both "keep", the project appears to corrupt itself, because after that, every time I try to build it again, the build fails and I'm granted with a very long error message (at the end of this post)
Since I was getting all these errors, I've decided to buy Prime[31] plugin thinking that it would make my life easier, but how wrong I was. Now I have another layer of indirectness and things are still not working.
