Still no. Even made sure I upgraded from 3.4.0 to 3.4.14. Tried both [new:{{ currentUser.id }}] and [new:1]. Can you please link to craft docs? I can't find that page.

<p>I have Notification entry with sendTo field and nViewed matrix:<br />
- viewedBy = Users field, limit of 1<br />
- viewedDateTime = Plain Text</p>

<p>User's don't see whole front end form, just a 'Mark as Read' link. The link uses js to populate viewedDateTime and submit form. My form:</p>

<pre><code>&lt;form id="update-{{ msg.id }}" method="post" accept-charset="UTF-8"&gt;
   {{ csrfInput() }}
   &lt;input type="hidden" name="action" value="entries/save-entry" /&gt;
   &lt;input type="hidden" name="redirect" value="{{ theredirect }}" /&gt;
   &lt;input type="hidden" name="sectionId" value="{{ msg.section.id }}" /&gt;
   &lt;input type="hidden" name="entryId" value="{{ msg.id }}" /&gt;
   &lt;input type="hidden" name="fields[nViewed]" /&gt;
   &lt;input type="hidden" name="fields[nViewed][new1][type]" value="viewed" /&gt;
   &lt;input type="hidden" name="fields[nViewed][new1][enabled]" value="1" /&gt;
   &lt;input type="hidden" name="fields[nViewed][new1][fields][viewedBy][]" value="{{ currentUser.id }}" /&gt;
   &lt;input type="hidden" name="fields[nViewed][new1][fields][viewedDateTime]" value="" /&gt;
   &lt;button type="submit" class="tx-11 btn bd-0"&gt;Mark as read&lt;/button&gt;
&lt;/form&gt;
</code></pre>

<p>When the first user from sentTo clicks the 'Mark as Read' link, they get added to the matrix. All good.</p>

<p>When the second user from sentTo (testing on a different browser) clicks the 'Mark as Read' link it overwrites the first users row instead of adding another row to matrix.</p>

<p>I've also tried using field <code>name="fields[nViewed][new{{ currentUser.id }}]...</code> to make them unique but still overwrites.</p>

<p>What am I missing?<br />
