Hi,
I recently upgraded to the premium Leetcode version where there is an "allow seen" button in the (old) mock interview starting panel. To my surprise, this appears to work a little different than I expected. Apparently, the option to (de)select "seen" problems only refers to those problems that I encountered during my mock interviews and not those that I did as normal problems. This means that even if I do not tick [ ] allow seen, then I mostly get problems that I have previously solved as normal problems (not in mock). I find this a bit annoying, because I mostly still remember the solution and want new problems. Please add this feature or adapt the "allow seen" function accordingly.
Thanks!
