Google Merchant Center performance reporting is getting 4 updates starting August 24:

• YouTube affiliate traffic will be segmented out - no longer lumped in with Organic (you might see organic decline)
• YouTube organic traffic definitions will change so they match established YT reporting standards (again, might cause a drop in organic when this takes effect) - when it drops, this one is gonna apply to historical data going back to July 1 of this year
• Product-level reporting for Google Ads will expand to include all ad channels/formats (expect an increase - here's documentation with more info about the changes)
• There will be new ways to segment performance data (this one is not launching on the 24th, but sometime in the future)
