A380 LHR- MIA Wifi and IFE packed up after an hour and could not be restarted - MIA-LHR 15K would not even recline manually! This was a couple of weeks ago, so Covid prison tray-style service. Food each way was pretty much inedible, and even the crew told me they were embarrassed to serve it. Club kitchen is now a shadow of its former self. Made a complaint, and two weeks later have not had a response.
