The non-beta version of Appodeal works great on Amazon devices. The GDPR beta version no longer supports Amazon builds. Vungle at least for me has very low fill rates for banners.

Hi All;
Thanks for pointing out Appodeal Rob. I sure respect all that they are doing for/with Corona. I think they are great. However . . .
APPODEAL
– I did spend a number of days testing/learning the Appodeal plugin back when it first showed up (before Appodeal bought Corona). And I decided to not go with it then because it effectively eliminated my direct (and successful) use of other advertising plugins. Plus, the “heft” of the plugin back then was about 37 Mb in my tests and I really couldn’t see that working for my players. I know that overall plugin size has come down with modularity. But even with the modularity, the note at the top of the Appodeal documentation reads:
"Important – Appodeal contains various SDKs for the ad providers it mediates. This means that you can not use Appodeal in conjunction with AdColony, AppLovin, AdMob, Chartboost, Facebook Audience Network, Flurry Analytics, InMobi, Unity Ads, or Vungle.
– Agramonte’s comment about the GDPR beta of Appodeal also makes me think that the Amazon support won’t be there for long. Is this the case, or am I in-the-dark on something? (often the case)
VUNGLE
Thanks, SGS, for pointing out Vungle. We actually do Vungle rewarded videos on both the iOS and Google Play devices. I guess what is throwing me on using Vungle for Amazon and using Vungle banners is that NEITHER is even mentioned in Corona’s Vungle plugin documentation (Vungle 5 - https://docs.coronalabs.com/plugin/vungle/index.html or Vungle 4 - https://docs.coronalabs.com/plugin/vungle-v4/show.html). SGS, could you point me to any docs that are relevant on this? Thanks.
Thanks for everyone’s input. Though it looks like I may only have Chartboost as a go-to.

Vungle documention here:

Just create a banner placement in the admin and follow the instructions above.
Hi Agramonte;
Thanks very much. I had missed that because I was searching for answers within the Corona site and documentation. 
So . . . outside of low banner fill rates, does this v.6 plugin seem stable/reliable in your short experience with it?
Best;
Steve
I have about 80% fill worldwide. 100% in all the main countries. I only use reward videos.
No problems other than the fill for the banner. Didn’t test on Android or iOS just on Amazon. I also plan to use it on Yandex and Apptoid.
As with all ad plugins there are some “issues”. Unfortunately the patch from Vungle is not until July 2nd!
Agramonte & SGS. Thanks for the great info from both of you.
On Vungle, I think I will punt for a month or two and revisit in about August.
Steve
@sgs I was just about to implement Vungle for my next game - releasing likely tomorrow… Do you mind saying what type of ‘issues’ one might expect from using Vungle in their games?
And the path you spoke of set for July 2nd, are those issues to be addressed by the patch?
Thanks
Bob
Various ANRs, sometimes the instance doesn’t initialise correctly and you don’t get ads (JAVA error about null pointers). Nothing too major.
SGS,
Thanks
So Vungle is the best choice right now when doing ads for Amazon builds? And there are adjustable banner ads available now also?
Wait Vungle has banners!
That’s not in the documentation!
I do not believe Vungle has banners. It’s a video ad service unless they’ve changed something.
Rob
No banners for Vungle.
