Why do some Merchant Center diagnostics errors disappear on their own after a few days?
The short answer
Most of those errors clear themselves because they were caused by timing, not by a real problem. Google crawls your site on its own schedule, so it can compare a cached old price to your new feed. The next crawl or resync fixes it. Errors that need a real change never vanish. ZenoX checks which kind you have first.
Most of them were timing, not a fault
Three clocks run at different speeds here. Your Shopify store changes instantly. Your feed app syncs on its own schedule, so an edit from an hour ago may not have reached Merchant Center yet. And Google crawls your live pages independently, whenever it feels like it.
When those clocks disagree you get an error that is technically true and practically meaningless. Google cached a price of 29 euros, your feed now says 27, so it reports a mismatch. Nothing is broken. The next crawl or a manual resync lines them back up and the error quietly disappears. A resync clears most of this kind within 24 to 48 hours.
Which errors never disappear on their own
Timing errors go. Real ones do not. An invalid GTIN stays invalid until you fix the field, because Google checks it against a real product database and no amount of waiting changes the answer. A missing returns policy stays missing. A policy violation stays violated. An image that breaks Google's standards stays broken.
The rule of thumb: if the error is about a value disagreeing between two places, waiting or resyncing might fix it. If the error is about something being wrong or absent, only you can fix it. Waiting on that second kind just burns days of lost Shopping traffic.
What to actually do instead of waiting
Open Merchant Center, go to Products, then Diagnostics, and read the exact error code per product rather than the summary count. Download the report so you can sort it. Then trigger a manual resync and give it a day or two.
Whatever survives that resync is real. Fix those one by one, at the source, before you request any review. Requesting a review on unresolved issues usually fails and slows down the next attempt.
ZenoX sorts the list this way on the accounts we take over. Half the scary error count is usually a stale crawl. The other half is the actual work, and knowing which is which on day one saves a week.
