You are experiencing one of the following issues
You may be experiencing one of the following:
The left sidebar is collapsed and your collections are no longer visible.
You can’t see your collections list in your workspace.
What to expect
In v12, panels in the left sidebar can be shown, hidden, or customized based on your workflow. This allows you to access relevant tools and information in one place, without switching contexts.
How to fix it
You can restore the left sidebar to bring your collections and other items back into view.
To do this:
View the footer options in bottom-right corner of the app
Click the Toggle left sidebar icon to toggle the left sidebar back on.
