Why has my question been deleted?

I am unable to share tracks from my TomTom Rider 420 to a new MacBook running macOS Mojave via bluetooth. I placed a question giving fuller details and asking for advice in the "Home › English › Navigation devices › RIDER" area. That question has now disappeared.

The 'My Discussions" link to the right of the topics still indicates that I have two discussions, but clicking on it only shows a much earlier one from April (which was never resolved). There is no mentioned of the one I posted several days ago, nor does it show up if I try to search for it.

May I ask why it was removed?
