Hello.
I heve not solved the issue yet even if I try the way you showd me.
The sample project “TestUMA.uproject” can not be displayed ads too.
I guess “CallBack” function doesn’t work well.
there are no response whatever I did.
My guesing is as shown below:
・ Because using Japanese Unreal engine4
・ Because there are some bugs for UE4.18.3
・ Because I have been taking elementary mistakes somewhere.
・ I need C++ knowledge to use this plugin? (I’m using Blueprint only project)
Please find the attached screenshots.

I hope I can solve this problem as soon as possible.
