How relavent to what? Are you concerned a Matrice issue may extend to DJI drones other than the Matrice?
I can’t open the Facebook page (closed group) so cant say anything with confidence.
What is known is that DJI reported a firmware issue with TB50 and 55 battery around November last year and issued an update. If this is what the article is about it should not be a concern for any DJI product other than those flying with those batteries.
