I have my default wishlist category set to my own creation instead of "unsorted". Recently, all items that I have added using the "+wishlist" option have been added to the "unsorted" category instead of the default wishlist category that I have created.

Yes, this just happened to me as well.

I switched to a different category for fireside and it still put everything in unsorted.

I've been having this issue too. But moving the items to another WL category is working for me at least. I just put everything in Unsorted and then moved it where I want it. It's an extra step, but there's a workaround for now until it gets fixed.

this is definitely still happening :c

Yes,still happening...
