Hi Cihan,
Thank you for providing the requested details.
I tested your ad unit IDs with our sample app, and can confirm that I was getting ads from it (see attached screenshots). With this in mind, you may want to try enabling a test device instead of using the test ad units for your ad testing purposes, and check if this would work for you.
As an aside, I had to delete your original post since it contained your app and ad unit IDs. Attached is a masked copy of your post for future reference.
Regards,
Ziv Yves Sanchez
