Iām also having this problem but this is like my first night with the monome.
Iām finding that some of the effects donāt recognise the Grid. Flin is the main one of these that Iām noticing. All others are intermittent.
I tried Sum which worked, including Flin so I know the monome works.
When I tried with the Ableton Push connected, all effects lost the ability to see the Grid.
Iām running Live 9.5, Windows 7, varibright 128 (currently sold Grid), and whatever the latest serialosc is. I assume 1.4
