I updated the Firmware on my MK4S (with MMU3) to "Firmware 6.5.3 (3.0.4) MK4S, MK4, MK3.9S, MK3.9". After I did that I get an error on my printer that the MMU is not compatible with this firmware. I looked at the website under the MMU  and the update is the same name and size. What am I doing wrong? Should I just revert back to the old Firmware?

Adding a modifier and giving them a different infill to cover the join is a bit slow when you have lots of bits butted up and beam interlocking only works with internal parts and not external.

When I have a model of something that has arms, legs, feet and other bits that are of a different colour even though I am using the same filament they sometimes break off at the place where the colour changes. Are there any settings that I am missing , or am I just asking too much of the slicer. Any help or ideas would be appreciated.
