You need to enable this experimental feature in 7.0.3:

Enable-ExperimentalFeature PSNullConditionalOperators

Hmm... I didn't think I had enabled any of them but that one option is turned on so I guess I did. Sorry for not recognizing that.

[rkeithhill]

No worries. :-)

Just an FYI

This experimental feature seems already included in 7.1.0-Preview.6.

User error. Didn't realize I'd at some point enabled this experimental feature on my Windows machine - I assume I did it though if so, no recollection and the others weren't enabled.

In any event, easy remedy to enable on Linux.
