This is the only ID that gives the switch option. I also tried my daughters' IDs.

On all, I tried 'Sell Similar' on active, sold and unsold items and all just threw up the bulk re-list.

On this ID I did the same thing and found the switch option on all, including the Re-List (which wasn't happening yesterday).

The auto free re-lists is not on any, including this one.

I suspect they're gradually closing them all down.
