OBB here but app won't load it and stay on the first scene

Hi everyone,

Everything was going fine but suddenly after a few update the split application binary option didn't work anymore.

I didn't change anything, I just put my apk and my OBB file on google play as usual and since then it doesn't work anymore. I only have my first scene even if it downloads all my app (with obb ~200mo). But I can't find the OBB on my phone after download. And if I put it manually it doesn't work either.

I don't know what to do anymore :(

Do you have any idea about what could happen? Maybe something in the manifest? Something else? Thanks so much for your attention.
