When you release an app, or if it's rejected during the review process, you can't make changes to the app until you create a new version of it.
To create a new version of an app:
Log in to the Developer Portal.
Navigate to the Your integrations page.
Select Create a new version.
When you create a new version of an app, Canva creates a complete copy of the existing app, including its metadata and extensions. Nothing is lost between versions.
If you create a new version of a released app, both versions of the app appear in the Developer Portal until the new version is released. When the new version is released, the previous version is no longer displayed.
If you create a new version of a rejected app, the new version of the app is displayed instead of the previous version.
