Gradient colour on ProgressCircle on mobile

Is it possible to set the progress colour of a ProgressCircle widget on mobile to be a linear gradient? Just putting "linear-gradient(red, yellow)" into the ProgressColor field doesn't work.

Tried the same thing on the header of a webapp but gets ignored. This is O10. Haven't tried on O11 just yet.

Edit: Just came across this for webapps and works. Don't know about mobile, though. the "-webkit" piece is what did the trick.

background-image: -webkit-linear-gradient(45deg,#002F6C 0%,#007096 100%);

Sorry, I didn't get a notification of your reply. That didn't work though unfortunately.

Hello Juan,
It will not work.
