What should be done in the above case?

Hi @jyj1127j,

I was able to replicate the issue you're facing, and it's likely that it's caused by a bug with the resolver. As a workaround, you can go to Build Settings > Player Settings > Other Settings and manually change the package name. That being said, I'll be marking this as a bug for now.

We're facing the same AmbiguousMatchException in our project.
There is a pullrequest with the fix for it #518
Is there any ETA for when the fix will make it into a release?

[Sebight]

Currently having this problem as well, any idea when this will be resolved?

@paulinon Could you elaborate, if this workaround still works? I would do anything to at least get rid of it for now. I tried it myself, but don't know where to continue from Other Settings. 😄
