Thank you for your reply. However, that skin showed up as being available to me prior to Nov. 25th even though it was actually locked. And some of the other stuff has been locked even though it said it was available. (e.g. Battle Pass "rewards")
On another note, I'm happy to report that all of the previously "locked" items from the Battle Pass suddenly appeared unlocked on Nov. 25th! Thank you, DICE!
On another other note... I noticed that when items disappear from the "Store" (and when unlocking a challenge reward but it still shows up as locked), running the "verify integrity of files" in the Steam Library seems to fix those issues. YMMV!
