I have a free WolframCloud account and wanted to use `Trace` in a notebook, but running it with a single expression always results in an empty list (`{}`). I thought perhaps I was just using it wrong, but copying & pasting the examples from the `Trace` documentation leads to the same result.

Is this feature only available in Desktop contexts, or am I missing something here?

Matt:

I have a paid account, and it does not work for me either.

It would be great if Wolfram added a bit more info to their function/feature documentation:

- Supported environments
- Supported versions

Have a great weekend
