Hello,
Recently the HMTL custom message template had a fix after working case #33541885
We are trying to use this simple html and we get an error on that field indicating "Please enter valid HTML text"
<p>Hello</p>
<p>This is an alert</p>
We need assistance on this issue
Release : SAAS
This should also work by adding another layer with the div tag to place the text in a section.
<div>
<p>Hello</p> -- no blank line in-between
<p>This is an Alert</p>
<p>alarm url: ${alarmURL}</p> -- example of a variable
</div>
Try with quotes around text as well
