Thanks folks. Will be getting back to this Sat. morning as had some wonky client project while this issue is for my own stuff.
Wrinkle I ran into is that the ACF field I’m using actually puts double
<br><br>
tags.
So would need to replace with
‘</apxh:p><apxh:p>’
And also replace
'<a href>'
with <apxh:a href>
and '</a>'
with '</apxh:a>'
I think I’m going to have to hire an ACF pro on this one!
