Hi all,
I've just signed up to say I have the same, 2017 Q3, got back off holiday yesterday and noticed no DAB channels would play, it's been in an indoor carpark for a week but I couldn't see how that would've affected it.. rescanned multiple times but still not getting onto D1, local channels work, so it must be something else wider at play as has been discussed..
Hopefully something can be found to resolve soon.
Also just found this discussing it here where there's a bit more info https://www.a1-forum.co.uk/threads/dab-radio.234074/
