There have been some posts about changes to the Infotainment functionality in the 2021 MY from previous years
The previous 115HP engine is not RDE2 compliant whereas the 110HP unit is, so presumably that is the reason behind the change - although there is a technical drop in horsepower it doesn't really translate into a performance drop - 0-60mph is 9.6 seconds for the 110HP compared to 9.9 for the 115; torque remains the same at 200Nm, with top speed dropping from 120 to 117 mph (both of which of course are far beyond the legal maxima (at least in the UK).
