PlayFabEconomyAPI.SearchItems() is weirdly slow. A catalog with only 3 items, 1 bundle, 1 currency and 1 store takes 1 second to retrieve. I would expect 0.2s or less. This is only 1 page. Imagine how slow it would be with 10+ pages.
All other API operations are super fast, so it's not my computer, ISP, VPN or similar.
