Whatsapi behaving erratic ! Sometimes it posts and some times it doesnt !

My latest posting issue is to groups - this has just cropped up.

I am doing

$w->sendMessage($gId, $msg); $w->pollMessage();

Response is

 tx  <message to="91xxxxxxxxx-xxxxxxxxxxxx@g.us" type="text" id="ey5VDDSVLUjC0" t="1448197487" notify="%82%9bg%3ct%9e%3b%c3%b9%c79qs%ab4%86%40%5b%95%b0">
tx    <body>Test Group Message</body>
tx  </message>

rx  <ack from="91xxxxxxxxx-xxxxxxxxxxxx@g.us" class="message" id="ey5VDDSVLUjC0" count="1" t="1448197609"></ack>

Thats it. No message delivery !

Can you please tell me what I must be doing wrong ?
