Quickbase Actions for Grid edit

That is actually not an uncommon misconception with Actions that they will not work on over ten records changing via an Import or Grid Edit. Actions make use of the API call ImportfromCSV so when multi record changes take place via Grid Edit a single ImportfromCSV action triggers from a single Action. It is still possible to trigger a number of other Actions and Webhooks all at once depending on how many individual Actions and Webhooks are in your table and overwhelm the rate limitations but Actions were designed to adjust for mass record changes. 

The most common reason that Actions fail in Grid Edit is usually tied to the Actions triggering criteria not being present on the Grid Edit report but it is present on the Form. Alternatively, this can also happen if the Actions firing would cause duplicate records to be created when using Grid Edit, for example if a single Grid Edit would generate two duplicate records in the destination table. If you open up the Action in your table and pull up the Error History does it give you an error message on why the Action is not firing or have you received an email warning you about hitting the Quick Base Action limit? If you are still having trouble troubleshooting your Action I would suggest putting in a support case with our Care team using the link here. That way they can look at the Action itself and see if they can help you troubleshoot what is preventing it from firing.
