Alert does not contain a supported visualization Splunk Mobile

[chandralinginen]

So i created a basic alert to test in SPlunk Mobile. just a stats count by host and trigger an alert to send to mobile.
I do get the alert on my splunk mobile app with title and app name (search). And when i click on it, I am expecting to see a table with host and count, and I receive an error saying "Alert does not contain a supported visualization Splunk Mobile". I havent selected any visualization initially.

After that I created one more alert and saved it as column chart and tested again. Nothing. Anything that I am missing here?

Double check that you have attached the correct dashboard for your test and that its visualizations are supported. The default visualization when creating an alert is None.
