I use it frequently (bought a game yesterday, in fact) and had around 50 games on there. Not only that, but I can't even add new games to create a new one. Will it restore automatically, or am I just out of luck?
Update (2/26/24): I am now able to create a new wishlist, but since I tried adding games while it was broken, I lost everything that was there previous to the mishap. It's a shame, really. I had a lot of indie games saved, which are the ones the names of which are difficult to remember, being not publicized as much. There are a lot of good indie games out there, and I like to support those developers as much as I can. Though I'm sure I won't have trouble finding new ones, it's still a disappointment.
