Can't post update to Test Flight (doesn't require review)

I need to post an update to Test Flight but I'm being blocked by the message saying App Review is closed for the holidays.


My app does not require app review -- it was already reviewed several weeks ago and I'm just trying to publish a minor update, the kind that always goes through immediately without another manual review. I knew about the holiday shutdown but didn't think I would be blocked from posting updates where no review was required. Is there a way around this?
