Admob reward Ad not showing

Hello fellow devs so I have implemented admob reward ads and I have already created an account and it has been approved. I have already got the admob app id and the unit id and already integrated them into the app. The problem is when I run the apk on my phone it does not show the reward ad. The image below shows how I implemented the reward ad. Could someone please point for me where the issue is. Thank you in advance.

You can find lot of similar issue on the forum, use the search bar and read the wiki page about the admob actions.

Yes, I already read the wiki and followed it step by step. I have also read related posts but still, can’t figure it out.

Sorry for this post. Apparently, evrything works fine
