Process Substitution not working with Linux 2 bash?

Question

Does the bash provided with AWS Linux 2 not support process substitution?  I have never used this feature previously, but now a circumstance has come up where it would be useful.  But even the simplest demo fails, e.g.:  
  
me$ cat <(date)  
sh: syntax error near unexpected token `('  
  
My shell say it's:  
  
   GNU bash, version 4.2.46(2)-release-(x86_64-koji-linux-gnu)  
  
And fwiw my shell in /etc/passwd **is** /bin/bash, and anyway /bin/sh is just a symlink to /bin/bash.  
  
Am I missing something?  Or is Linux 2 really delivered with a bash that doesn't support this?

I understand what you are saying here, however:  
  
1. My shell really is bash, as I stated originally.  Both "bash --version" and "sh --version" identify themselves to bash, as I quoted.  
  
2. shebang does not enter into the question; It doesn't work right from the shell prompt either.

Still, that gave me the clue I needed.  Thanks!
