Why can't I find the GA plugin in the App store?

For new stores registered after March 5, 2021, Google plugins in the App store are all merged in Marketing > Google. If you need to add Google Feed or Google GA data tracking code or Google Ads, you can implement it in Google section. But if it is a store registered before March 5, 2021, plugins still exist. If you need to use the new Google section, you need to remove the data in the old plugin.
