When cleaning the bike the other day, I discovered a lot of play in the whole front mech. If you grab the chain guide at the back, you can rock it in both ways by something like 5mm or more. It's not only the chain guide, but also the 2 paralellograms that have play in them. My Chorus front mech has hardly any play in it... Shifting is still great, but it's very surprising, as the front mech is only a couple of weeks old, and when you now what kind of forces thet DI2 front mech applyies, you should expect it to be rock , and rock solid. The support bolt to the frame is there for something after all! So I wonder if everything is OK with my front mech :?: I can try to upload a short clip to youtube this evening if you want.

mine is solid with 0 movement. Have you tried to contact Shimano? They usually reply via Facebook
