Hello,
I try to create a release on Google Play console. I'm able to upload the new APK version. But I don't know how to upload the expansion file (i.e. the zip file that is supposed to be attached to the APK).
In the previous version of the Google Play console, there was an add icon (+) that is no more visible in the new version. So I'm stuck.
Could somebody tell me how to do that, please?

Hi Dominique,
The add icon (+) has been replaced by the "hamburger" icon (three horizontal lines).
I uploaded an extension file a few days ago and am still waiting for the app to be reviewed.
The console appeared to be asking for .obj extension file. I uploaded the .zip produced by Pubcoder and it went through. I'll have to wait and see if it passes the review.

Hi Phil,
Thanks a lot for your piece of advice.
Actually, it worked for me. I hope it will be the same for you too!
