What the page says
- Automations may not work for products that change more than once per day.
- Google may also stop updates if the total number of detected mismatches becomes too large.
- Per PPC News Feed’s Hana Kobzova, the help page was revised on September 27, 2026 to add the mismatch language.

Our read
If your prices or stock change several times a day, make sure the feed and the landing page agree at the moment Google checks. Review diagnostics for mismatch warnings and consider whether intraday price changes are worth the risk of a disapproval.
