It’s worth pointing out that RevMob “may” have recovered. Given the lack of chatter on here and elsewhere to that effect - I doubt it. Unless someone can comment to the contrary?
For iOS I use iAds, Adbuddiz, AdMob (sorry that yours is disabled) and Vungle. For Android I don’t bother. Android does not monetize well in my experience. YMMV of course.
I’m presently focusing on android. Cause for iOS I’ll have to arrange for a macbook 
(I’ll try to arrange it soon)
Anyways thank you so much @MAS1 for your time. 
I am seeing very low eCPM on Revmob. Don’t recommend it. Try using Chartboost instead.
So, anecdotally it appears not to have recovered.
When I closed my account with them in the summer, I got exasperated with the installs that were “never credited”. When I queried it with RevLoss, I was told that it was because the campaign in that instance was CPC rather than CPI. Ouch! The dashboard was very misleading.
Okay… So I tried chartboost. But now during compile time, I am getting the error that chartboost is not supported for this package.
It is not compatible with corona starter I guess 
[feeling frustrated]
Now i’m thinking to give Adbuddiz a hit. How is it? If not good, then please suggest an alternative which is compatible with corona starter
Like everyone mentioned. Don’t bother with Revmob. They’re pretty useless now. Chartboost is the way to go for interstitials and Vungle for videos. If you’re using iOS, then use iAd too.
I’m unable to use chartboost [Maybe because I’m using corona starter].
So now I’m using Adbuddiz for interstitials and Vungle for videos.
