Fixing Issues with Update Attributes Action in Magento

I have issues with the "Update Attributes" action, what can I do?

InfoPlease keep in mind that Update Attributes is a default Magento mass action that is not affected by the Mass Product Actions extension, which can be confirmed by disabling our module. If issues are still faced with it when Mass Product Actions is disabled, we may recommend reaching out directly to Magento. However, there are also a few standard checks worth noting.
1. When Update Attributes action is used, the data update process isn't performed instantly, instead it is sent to queue to be performed via a cronjob. The action itself can be interpreted as working if you see the following messages on the product grid page as a result:







After this, it is necessary to wait for the corresponding cronjob to be run if Magento cron is set up in your instance. In case Magento cron hasn't been configured yet, run the following command from your root Magento directory to run cron manually:

php bin/magento cron:run

Once cron is run, you may check your products for updated attribute data.

2. If you try to update attributes via mass actions, but the attempt fails before you even see a success message, 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.
