Hi Can Anyone Please Suggest A Good As Network for my app

So I’m Stuck At Monetization phase of my app.I need a good and legit ad network for my app I have tried networks given below but they didn’t worked

Start app - Impression, Revenue not showing from last week
Unity ads - literally 0.78$ ecpm for rewarded ads
Facebook ads - Showing Ad Expired error I guess SDK not updated
Admob- Lack Of Ad Inventory

So I used tapjoy ads
It’s offerwall is working fine but Rewarded ads are showing impression is counting but revenue not updating

can any one help me to fix this or suggest any other ad network please help I want to complete my app​:sweat::sob:

How many active installs do you have? Also how did you use Tapjoy?
