first post here and not sure if this is in the right section however I am having a (possible) problem following an update to my Ultegra Di2 with view to add the syncroshift functionality. I have updated everything, however when clicking on Shift Mode Setting button via E-Tube software I receive an error saying the FD & RD is not on the latest version? I then try and update everything again and it tells me that everything is on the latest firmware?
So, my question is - do I have an issue here or are the FD&RD just too old or not compatible?
The fullsystem details are as follows;
SM-BTR2 - 3.0.10
SM-EW90-A - 3.0.4
FD-6870 - 2.6.2
RD-6870-SS - 2.6.3
ST-6870-R - 3.0.0
ST-6879-R - 3.0.0
