eBay won't let me log in with Brave

I’ve been using Brave for several months and like it very much. However, if I try to use Brave to log into my eBay account, eBay says my user ID and password don’t match. I tried disabling the cookie blocker in Shields, and that didn’t help. I don’t have this problem when I use other browsers. Can anyone suggest what I can do to correct this problem?
