I have just answered a tapping test in https://www.memrise.com/course/135686/communications-comunicazioni/11/ and the entry is
il sintonizzatore = audio receiver, tuner
I was shown the English and answered by tapping “tuner” and pressed continue and it told me I got it wrong.
I have just checked and I DO have “_tuner” and an alternative.
Surely alternatives should be accepted as correct for tapping as well as typing?
