These script actions are run in the background. A notification bar will be displayed, which the site creator can click to view the status of the actions being applied.

+For example, if the site already has a list with the same name that the site script is creating, the site script will only add missing fields to the existing list.

+We'd previously capped the limit of site script actions to 30. This remains the limit for scripts applied synchronously using the [Invoke-SPOSiteDesign](https://docs.microsoft.com/en-us/powershell/module/sharepoint-online/Invoke-SPOSiteDesign?view=sharepoint-ps)  command, but based on customer feedback and support for additional actions we have bumped this limit to 300 actions (or 100,000 characters) when the scripts are applied asynchronously (either through the UI or using the [Add-SPOSiteDesignTask](https://docs.microsoft.com/en-us/powershell/module/sharepoint-online/Add-SPOSiteDesignTask?view=sharepoint-ps) command).
 
-For example, if the site already has a list with the same name that the site script is creating, the site script will only add missing fields to the existing list. Also, please note that site scripts are limited to 30 cumulative actions (across one or more scripts that may be called in a site design). This includes subactions.
+There is also a limit of 100 site scripts and 100 site designs per tenant.
