I was bitten by this bug before you: https://github.com/jgm/pandoc/issues/7723. The fix should be in the next release of pandoc.
Hi,
consider this MWE:
```
Test.[^1]
Test![^2]
Test!^[asdf]
[^1]: asdf
[^2]: asdf
```
Running pandoc on this example gives me this error/warning:
[WARNING] Note with key '2' defined at exclamation-bug.md line 7 column 1 but not used.
I’m on pandoc 2.16.2
Is it possible that the exclamation mark breaks the footnote definition? An inline footnote works just fine here.
