On my 2015 mk5 Mondeo I had to get an insurance call out to my windscreen due to a stone chip...A £10 repair was carried out by the recommended glass fitting company...Since it was done, on the first frosty morning I noticed my front heated windscreen wasn’t clearing the ice. (It previously was working perfectly)....Can anyone advise whether the windscreen element got damaged as a result of the repair.

Possibly in some trivial kit areas but not IMO with screen heaters and them having enough intelligence not to burden a poorly charged battery.
Far better than the cold fingers from scraping off the ice or the refreezing on the very cold screen if doing the tepid water trick, inbuilt screen heaters I find great.
Plus remembering back to fixed jet carburettors icing up after a few 100 metres on those cold damp mornings I for one would not give up the clever technology built into the cars we have today.

It is called load shedding. To reduce emissions the manufacturers use software to take load off the engine during certain drive cycles. Your alternator can account for 5% of your engine power at certain times. If this coincides with a heavy load requirement for the driveline then the car will turn off certain big current devices so that you effectively reduce the emmissions by 5%. This is usually not noticed by the driver as they reduce power for stuff that you dont notice, i.e. they reduce the speed of the blower fans and turn off heater elements, returning them to normal operation once you resume a cruising mode.
I suspect that your battery was down on charge so your alternator was busting a gut to get it to a healthy state of charge, in order to meet its emissions requirements and get your battery back to a healthy state the car had no option but to turn stuff off.
