New firmware updates for all parts today. There's also mention of a v2 app that allows fine tuning of the position for each derailleur (hopefully that means live fine-tuning, as that's probably the biggest setup issue with the groupset currently). The v2 app doesn't seem to be available yet but I will do the firmware updates once it is.
EDIT: Did all the updates. Right shifter firmware reset the settings on it (so you'll have to configure buttons again). The new app is available and FINALLY ALLOWS FOR LIVE FINE-TUNING!!! Better late than never. Shifter firmware updates apparently now increase battery life, and the RD ANT+ profile has been updated related to the battery settings - hopefully that now means it shows low battery at a lower battery percentage (rather than the 50% it was before).
