I am experiencing the same issue - Google Merchant Centre is throwing up pricing errors as I sell in metres on Shopify and cm on Google. It was an ugly solution but at least it worked. I want to maintain products from Shopify and NOT edit them in GMC.
Topic summary
Google Fields in the product “More actions” menu disappeared. Shopify support confirms it’s deprecated; editing must now happen via the Google sales channel’s product editor, with some variant option names auto-mapped (Size, Color, Age Group, Condition, Gender).
Merchants report the new editor lacks filtering/search and increases Google Merchant Center (GMC) errors. Support advises bulk editing after making products available to the Google channel.
Workarounds:
- Append “&app_context=1780363” to the product bulk editor URL to expose Google columns.
- Define and pin product metafields (Settings > Custom data > Products > Metafields without a definition) so fields appear on product pages; presets for gender, age, condition help. Entering full category paths or numeric codes works for some, though category syncing is inconsistent.
Newer update: In Google sales channel > Manage Products, checking the Google column enables direct field editing and saving. Some still see Google Product Category not syncing; GMC may auto-assign when blank.
Outcome: The old menu hasn’t returned. The discussion is ongoing; a key open question is whether to remove now-duplicative product metafield definitions. Screenshots in the thread illustrate the steps and interfaces.
