source/includes/try-next-warning.rst

+   The `tryNext() <{+api+}/classes/ChangeStream.html#tryNext>`_ method does not
+   automatically update the change stream's `resumeToken.
+   <{+api+}/classes/ChangeStream.html#resumeToken}>`_ If you require an updated
+   ``resumeToken``, use the ``next()`` method.

The `tryNext() <{+api+}/classes/ChangeStream.html#tryNext>`_ method does not

automatically update the change stream's `resumeToken.

      - ``next()`` to request the next document in the stream

There's a warning below the tabs section on line 117/118 (not this one, but I can't comment directly on it), that I would move into the other tabs, because:

I don't think it's only relevant to the Idiomatic Iteration and Event tabs (ask tech review to confirm)

It looks a little odd to have two warnings appear in a row

I believe Iterator mode applies to idomatic and manual iteration, but I will double check as I agree stacking callouts is odd.

This is relevant to all tabs because it's a warning not to mix the modes defined in each tab, basically.

What do y'all think of moving this above the section altogether?

I can do that, under where it says "read events from change streams by iterating over them or listening for events." The warning can emphasize the or.

Yeah, I think that works nicely. Thanks
