<p class="MsoNormal">Hi Even,<o:p></o:p></p>
<p class="MsoNormal">It’s working now, for my two test cases, --- as long as there’s a
<span style="font-size:9.5pt;font-family:"Cascadia Mono";color:#A31515">TOWGS84[0, 0, 0, 0, 0, 0, 0]</span> field in the WKT w/ the geoid grid. I’m guessing that ties the grid to the datum/geogcs of the containing compound CRS?<br>
Thanks!<br>

<p>That was indeed an entirely different issue. Fix queued in <a href="https://github.com/OSGeo/PROJ/pull/3147">
