After updating my Anki to 2.1.42, I no longer have the option to Reschedule cards. Currently, the only options in my top bar are “Set Due Date” and “Reposition”, neither of which allow me to reschedule a card as new. In the past, I had an option to “Reschedule” which would allow me to set a card as new. I have the ReMemorize add-on enabled. Below are the pictures of my rescheduling options–so far I haven’t figured out how to get either of these options to allow me to reschedule a card as new.
You now have the Forget menu item to do that.
