Here are a couple of reasons why your prayer request might not be getting captured by Gloo.
Make sure that you are using correct spelling.
Make sure to say something like "I have a prayer request" or "I need prayer" before sending the request.
If the language isn't clear enough that it is a prayer request, the message may end up with the "Needs Response" status instead of "Needs Prayer."
Words that should trigger the Prayer feature are anything like "pray," "prayer," "prayer request," "pray for me," etc.
