What is your feature request?

If the activity state == 'playing', increment the timestamp on the activity cards every second to give the illusion of the stream progressing. Re-sync the timestamp to the correct time when the card refreshes.

Are there any workarounds?

No response

Additional Context

This would match the same behaviour of the activity cards on the web UI.
