I am having the same issue on steam deck. Tried different protein layers with same result. HOWEVER, what some people are saying on here about the server thinking we are logging in from a Mac makes sense. While those without a Mac sub can’t log in at all, I have Mac version up to ShB in addition to my ew PC and PS5. It’ll let me log in and play ShB content but not EW, which if it’s logging in thinking I’m on Mac, that would make sense.
