Unity Levelplay does not work on mobile testing device. How can I fix this?

I’ve been working and researching for/on this for hours now and I seem to be losing my sanity.
I want to do the Ads Integration through Unity LevelPlay aka IronSource and nothing is working out. There’s no good doc.

I’m at a point where I have an AdsManager without Compiling Errors, a with Ironsource connected testing device and the IronSource Plugin installed in my game. Everything’s ready, but when testing Levelplay/Ironsource doesn’t seem to even exist in my game.

Though I don’t have a lot of experience, I really put a whole lot of blood sweat and tears into this (a lot of tears haha). Please help me, someone.

I’m exactly the same here mate. Found any resolution?

Nah sry. I’ll just use Google AdMob in the future.

Please tell me you found it or I cry

It looks like the Levelplay SDK is not imported correctly. Could you please run “Force Resolve” as below and try again?
Go to: Assets → Mobile Dependency Manager → Android Resolver → Force Resolve

Thanks

Hi!
I’ve been using it with the latest version of Google Play and Firebase on the latest Unity 6.3 and haven’t had any problems, so please double-check your package installation. Good luck!
