Tadpole Spark Grid by Angry Koala not working

[kcantor]

Trying to add the Tadpole spark grid to a report in the app. It works in desktop but is blank in the app. Same data source, same filters, same fields. Any idea if this was the victim of a change in code?

Update: This no longer works once the desktop version is updated. How can I get word to Angry Koala? I tried sending a message but received no answer.
