Bug LevelPlay crash on startup on ios for some adapters (unityads sdk for example)

I did dozens of builds and lost countless hours to try to make Levelplay works (I strongly advise doing it imo it's not ready, documentation changes regularly and is missing crucial steps)

I'm building Ironsource Levelplay sdk using unity, it works fine on Android but when I build and launch on iOS the app crash on startup. I tested many many things

Including changing the build properties and adding framework manually but it still crashes.
What is odd is that I can find the file in the IPA .

Do you have any ideas ? I'm getting crazy over it

(support doesn't answer me so don't tell me to contact ironsource)

 

@jcGrenier do you know who can help me on that ? I believe it's something simple but what it is I can't tell.
I tested with success admob, vungle, ironsource, applovin, but some are crashing (unity ads adapter for example)

 

Thanks, I managed to make most of levelplay work but with tremendous effort,
and the reward seems negative now (less ecpm with more sources )

 

Hey @rbitard did you manage to integrate Meta/Facebook as well? I'm currently having issues with them, tried every support email in the world lol

 

I managed to do it with tremendous efforts, and I don't even know what I did that allowed me to succeed.
What I encourage you to do is doing this 1 step at a time, validating each step, and if something is wrong, read all the documentation around it and make a support.

For now the ecpm is not worth it but I'll check again in 1 or 2 weeks if it's increasing, (I lost nearly half my revenue but I don't have a lot of users that have switched yet so that might explain)

 

Got you. Do you have Facebook for both platforms iOS and Android?

 

Yep I have meta ads. They barely win the bids and they are quite low already, around 2-3$ ecpm for interstitial french users. Really not good for now, I had way more with unity mediation and admob

 

Got you. Maybe you would be willing to chat or help me out? I have managed to do make the Meta for android, however, for iOS I get "no fill" error. Let me know!

 

Sorry I can't help you on this (I will probably switch because the ecpm is still very bad compared to unity mediation)
No fill probably means that meta doesn't have any ads for you not that it doesn't work, (I get it a lot with admob since I use levelplay)

 

Hi @rbitard,
I can relate to much with your line, I also lost about 40-50% of my revenue by using Ironsource + Unity LevelPlay, I am also in search of another mediation partner to switch can you suggest some of them? also did your eCPM goes up after few days of using Ironsource? Please Let me know

 

it did go up but it took several months and I'm not sure if it's up because it got back to what it was before or I simply got more users playing.

I'm implementing google admob right now, I hope it'll work flawlessly, in test it appears to work fine (ads preload fine compared to ironsource that never preload anything oddly enough even when I ask it to)

Admob adapter system is very odd though and difficult to know if it correctly works, we'll see

 

Thanks for the reply, I also transitioned to Google Admob Mediation now, and now getting a very good eCPM than ironSource and Unity's favorite LevelPlay, on a day when I get up to 2500 downloads a day (& 4000 impressions) I earned about $1 from ironSource, and previously with these many downloads and impression no., I was getting around $ 20-25 (with unity mediation - it's gonna deprecate soon)

Though I am happy I am getting the same eCPM (thanks to Google Admob Mediation) & the crash rate also decreases by 55%.

 

I'm migrating my users to admob and it's day/night for the moment with a very big increase in ecpm. As I said earlier I'm 100% sure that ironsource prioritized their own traffic with very low ecpm. Before switching from unity mediation (which was awesome btw) to ironsource levelplay I had a lot of good traffic from admob. After the migration I had a lot of traffic from ironsource . My first numbers with admob are quite good I hope it stays that way when all my users are migrated

 

Are you able to share what you did to get this working? Like others here, I've been able to get Android working but my iOS version crashes instantly on startup with no crash log reports. Works fine in the editor, builds fine, uploads to testflight fight fine. But on my device (iPhone 14 Pro) the app crashes instantly as soon as you open it.

If anyone has any solutions please share!

 

Sorry to disappoint you I left this solution now for google admob, it's not perfect but it's way better overall
