Popup window login flow using JavaScript SDK

Thanks for the reply, I’ll give session storage a shot and see what I can do there. Regarding this, though:

That SDK hasn’t been updated or maintained in a while (3+ years), unfortunately, so this may be an unknown bug.

Is there a different web/JavaScript SDK that I should be using instead? I didn’t see any indication that this one was deprecated but I’m happy to switch to a more supported one if it’s available…
