Way too easy to break Teams Files features
When you create a Channel, it creates a corresponding folder in SharePoint with the same name.
If you make any changes to the Channel name, the change does not flow through - the folder keeps the original name which will be confusing for system users.
The next thing the user will naturally do is go to the SharePoint view and change the name of the folder to match the new name of the Channel.
But when you change the name of the folder from the original name, it completely breaks the Files tab which then says files can't be found.
If the channel name changes, its SharePoint folder name should be changed with it automatically. And system users should not be able to change the folder's name in SharePoint view and so easily break the system.

We would also like to see a change here. Perhaps it could be possible to explicitly name the Sharepoint folder from within Teams, so that the link can be maintained manually.
