Editing I am not able to edit my campaign (section)

=== Common use cases with examples ===
The inability to edit a campaign can occur in various situations:

- **Old Campaigns**: Retroactively trying to edit a saved campaign that was created in the Classic Designer.
- **Template Selection**: Selecting a template during campaign creation without realizing the impact of choosing the Classic Designer.

For instance, if a user created a campaign titled "January Promotions" using the Classic Designer, they may struggle to edit it as required. By switching to the Email Designer and re-creating the campaign, they can seamlessly make updates and changes.
