Leadbolt ads not showing

beginner to this site try to make app and implement ads but admob not showing ads so i decide to switch ads platform to leadbolt at the time of test ads it was working fine but when i live my ads ads not showing help me with this

Yes thats because they have very low advertisers and targeting is also not that good. Use admob just check the error and search on youtube.
and there is a advantage that most of the videos are in hindi so you will understand it easily.

yes bro leadbolt is very bad no earning from leadbolt i use it some days but till now 0 earning
