Which action is generally recommended if you face issues with customizing templates?

Copying and modifying an existing template is generally recommended when facing issues with customizing templates because it allows you to retain a working version of the original template. This approach minimizes the risk of errors that may occur when edits are made directly to an existing template. By starting with a copy, you have the freedom to experiment with changes without disrupting the original settings that may be critical for other uses or processes.

Additionally, this method provides a clear way to track modifications. If the changes do not yield the desired outcome, you can easily revert to the original template without losing any previous configurations or settings. This practice promotes better management of templates, allowing for iterative improvements and adjustments based on specific needs and circumstances while ensuring that foundational templates remain intact for reference and use.
