Banner Error: Placement could not be found

Unity Services

Hello,
If I try to use unity Ads to show a banner ad It works in the editor and shows me a test banner but on the android build the test banner does not show. I get the following error:
Banner Error: Placement could not be found
I load the banner only after initialization is complete and this is the code I use to set it’s position if it’s relevant:
Advertisement.Banner.SetPosition(BannerPosition.BOTTOM_CENTER);

The placement ID used by iOS and Android platforms should be different, please check whether the placement ID you are using is correct.

Thank you! For some reason the placement ID’s were deleted from the editor. After I put them again it is working.
