I used the Annotation.Create API to create this annotation using a test user account in our DEV environment:

<ishobject ishref="GUID-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" ishtype="ISHAnnotation" ishannotationref="9000187">
<ishfields>
<ishfield name="CREATED-ON" level="annotation" xml:space="preserve">16/04/2025 18:29:11</ishfield>
<ishfield name="MODIFIED-ON" level="annotation" xml:space="preserve"/>
<ishfield name="FISHSELECTEDORIGINALTEXT" level="annotation" xml:space="preserve">Assumes the default line is set to the desk phone.</ishfield>
<ishfield name="FISHANNOTPROPOSEDCHNGTXT" level="annotation" xml:space="preserve"/>
<ishfield name="FISHANNOTATIONTEXT" level="annotation" xml:space="preserve">Replace with conref: GUID-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/GUID-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx</ishfield>
<ishfield name="FISHANNOTATIONCREATOR" level="annotation" xml:space="preserve">rachel.owlglass</ishfield>
<ishfield name="FISHCONTENTOBJLOGICALID" level="annotation" xml:space="preserve">GUID-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx</ishfield>
<ishfield name="FISHCONTENTOBJVERSION" level="annotation" xml:space="preserve">1</ishfield>

<ishfield name="FISHANNOTRESOLUTIONTYPE" level="annotation" xml:space="preserve"/>
<ishfield name="FISHANNOTRESOLUTIONTEXT" level="annotation" xml:space="preserve"/>
<ishfield name="FISHANNOTATIONCATEGORY" level="annotation" xml:space="preserve">Comment</ishfield>

<ishfield name="FISHANNOTRESOLVEDBY" level="annotation" xml:space="preserve"/>
<ishfield name="FISHRESOLVEDREVISIONID" level="annotation" xml:space="preserve"/>
</ishfields>
</ishobject>

It does not display in Review Space when I log in as the test user.

I created a similar annotation in Review Space using that same test account:

<ishobject ishref="GUID-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" ishtype="ISHAnnotation" ishannotationref="9000214">

<ishfield name="CREATED-ON" level="annotation" xml:space="preserve">16/04/2025 22:33:46</ishfield>

<ishfield name="FISHSELECTEDORIGINALTEXT" level="annotation" xml:space="preserve">Assumes the default line is set to the desk phone.</ishfield>

<ishfield name="FISHANNOTRESOLUTIONTYPE" level="annotation" xml:space="preserve"/>
<ishfield name="FISHANNOTRESOLUTIONTEXT" level="annotation" xml:space="preserve"/>

<ishfield name="FISHANNOTRESOLVEDBY" level="annotation" xml:space="preserve"/>
<ishfield name="FISHRESOLVEDREVISIONID" level="annotation" xml:space="preserve"/>
</ishfields>
</ishobject>

Why does the annotation created with the API not display in RS, but the other annotation created in RS does?

Thanks,
