Why is the login link missing on mobile view of my store?

Hey y’all!

Our shop is experiencing some weird behavior as of this morning, and I’m not sure whether it’s a Shopify issue or a theme issue. Basically, mobile users don’t see the “Login” link in the shop menu, only “My Account” and its subitems. Everything is normal on the desktop version. Hopefully these will illustrate what I mean:

Everything has been apparently working as normal until this morning, though still waiting on confirmation on that, when the shop owner contacted me about it being difficult to get to the login page for mobile users (which is the majority of our business). They can tap on “My Account” again or “My Wishlist” and be prompted to login, but apparently it isn’t an intuitive next step for most people.

Is it Shopify, Pixel Union (our theme creator), or something else? Any ideas? TYIA!

I don’t see a way to edit my original post, but I’ve been told this has been happening for a while… like, months, maybe even a year. They just didn’t think it was a big enough of a problem to tell me until now. :face_with_tongue:

The question still stands, though: Anyone have a clue as to why this may be happening?
