R6: do you see the enhanced (IBIS) IS icon with RF 24-105 L IS?

With my 24-104 f4 L IS mounted on my R6, I see the <hand> IS icon displayed. However, I don't see the <hand>+ icon. I do see the <hand>+ icon with my RF 85mm f2 IS. According to webs, the 24-105 is compatible with R6 IBIS. otoh it's very unclear form docs what the "+" even means. Do other folks see the plus with that lens on their R6? Thanks.

I can answer my question now, in case anyone else has the same issue:

Answer is that RF lenses have firmware in them, and that firmware has to be updated in order to enable IBIS on the R5/6 whith that lens mounted.

Pro tip for Canon software devleopers if you're reading : implement a version check feature in the camera so it says "you've mounted a lens that has old firmware and so IBIS won't work", instead of inscruptably and mysteriously just disabling IBIS.

I got my RF 24-105 f/4 about 3 months ago, and it shows the hand and + symbols together on my R6 units. The firmware versions are as follows:

Camera: Ver. 1.4.0

Lens: Ver. 2.0.6 from my understanding this is the firmware that works to provide both IBIS and lens stabilization.
