In case anyone is interested, GBBO is back on Netflix this season. I've watched the first two episodes - they drop a new one every Friday. Despite all the changes in personnel, it's still the same GBBO. For the past two seasons, they have been producing in a bubble so the bakers don't go home to their own houses every week. They do have a practice tent, however, it was mentioned in the last episode.
Interesting. I saw ads for it on Netflix and now I cannot find it. Not sure why it was pulled from my feed. Might be because of my VPN which sometimes causes problems with streaming services.
