Sadly I've got this problem too. My recollection was it started after my last update to the Garmin system in my 2018 CRV, but that was about early April, so might have been a coincidence and it might well be the date that is important for it stopping, not the update (which was my second update and has worked first time both times, so I don't think it is anything I could have done wrong. As I only did shortish journeys in April/May, I didn't notice the traffic not working, but on the M25 last week I was caught in a bad hold up and wondered why I hadn't been alerted, only to notice the traffic was greyed out rather than showing red/amber/green as normal when working. It is clearly switched on, finds the Trafficmaster signal after something like 30-60s, but won't get info from it.
I've bought nothing but Honda cars and motorcycles since about 1995. I am minded that this might be my last over this issue, if it's true it has stopped working because Honda Europe wouldn't pay, despite it clearly having a lifetime subscription according to my car.
