Just switched my Google Shopping feed source from WooCommerce to a new app with more flexibility. GMC shows everything approved - no issues flagged. But all my Shopping campaigns using custom labels are suddenly showing zero products.
Is there a delay while Merchant Center syncs with Google Ads? Or should I be looking elsewhere in the setup? One thing I'm wondering is whether the new app might be outputting the custom_label fields differently - maybe a formatting mismatch or empty values that don't register. I've checked diagnostics and can't see anything obvious.
Anyone else hit this after changing feed sources? Usually how long before products start flowing again?
