I’m unable to update attributes on multiple products, what can I do?

Please, keep in mind that Update Attribute is a default Magento mass action that is not affected by the Mass Product Actions extension.
If you try to update attributes via mass actions, but the attempt fails, then one of the reasons may be that the session size has exceeded. During this mass action, Magento gets product IDs from the backend session, therefore, it’s recommended to check Stores → Configuration → Advanced → System → Security → Max Session Size in Admin:



After the setting is disabled, the attributes will be updated successfully.
