Recent changes to automatic relisting

For years now I have had the option of automatically relisting a CD or LP if it did not sell the first time. I simply clicked a box. This option vanished this month. I assumed from what I read that 8 free relisting were now automatic and, rather than opt in, one had to opt out. I have just discovered that 100+ of my listings have not been relisted. Is there some procedure of which I am not aware? eBay did not advise of any changes.
