Things I’ve done to figure out my issue

• I used upgrade-helper to do my upgrade.
  https://react-native-community.github.io/upgrade-helper/?from=0.76.3&to=0.76.5

Upgrading version

0.76.4

Description

Till version 0.76.4 we had "packageManager": "yarn@3.6.4" mentioned in package.json.
But this has been deleted when upgrading to 0.76.4 and later versions.
Should we use the default Yarn Classic (1.x) from 0.76.4?
Are we supposed to run corepack disable now and then use yarn?

Reproducible demo

https://react-native-community.github.io/upgrade-helper/?from=0.76.3&to=0.76.5
Here, both "packageManager": "yarn@3.6.4" and .yarnrc.yml files are deleted.

So?? why is this? any problem with yarn v3?

[eduardo-santos-tribia]

I'm also trying to find an explanation or the commit and pull request related to this. It's confusing that they just removed this without providing any info.

Is it optional to remove? What is the impact of keeping or removing it?

[emirariemir]

The .yarnrc.yml file is also removed with the version 0.78+ too. I wonder if that's an optional removal or not.

[scosmanagraz]

I struggled to find the reason why both "packageManager": "yarn@3.6.4" and .yarnrc.yml files were deleted but it might have something to do with yarn 2+ not being well received.

I recommend switching the package manager to npm or pnpm going forwards.

Does anyone have the answer to this? Is it optional?

I have just migrated RN from 0.72.17 to 0.77.3 and the upgrade helper tell me to remove "packageManager": "yarn@3.6.4" and .yarnrc.yml, too. If I did not remove it and use yarn 3, I can't build android project. If I use yarn 1.22.22, I can build project successfully. But due to remove it, now my CICD broke, the CICD still run in yarn 3 and I can't force it to use yarn 1. Anyone has the same issue?

@DawnNguyenAhiho Had upgraded to "react-native": "0.76.4" with "packageManager": "yarn@3.6.4", and it was working fine in that version.

@jerinjohnk how about 0.77.3 I have to use it because I'm trying to adhere Google Play policy that require every app to support 16KB page size
