Why no EVA flights shown in United app?

I’ve been looking at flights to/from Jakarta out of SFO. Really strange to me that the United app will not show options through EVA, which actually offer really good options for my schedule. The United app mainly turns up ANA options (Singapore to a lesser extent), but they also show trips that feature a leg on NON partner airlines like Garuda Indonesia/Cathay Pacific, and it’s wild to me that they’ll show non partner airline flights when not showing any for a Star Alliance member. Anyone know why that is?
