@Edent This change - https://github.com/home-assistant/supervisor/commit/d23bc291d5c89074afaaf668023ce73193c2c92d - was in the most recent Supervisor release (which was cut 4 days ago)
I'd be willing to bet it's that.
It would also explain why it's only Supervisor users who have complained in that ticket so far - the change above was in supervisor rather than in core
