Kinda, there is a fundamental change in their API as they switched from username to email as identifier for API calls. We'd have to adapt our linking logic there specifically for this site, unfortunately there is no easy fix for that on our side with the logic being as it is.
We hard-require the username field throughout that logic. I was thinking about hacking our (wechall) side to always store the email in the username field for this Site, which should be a workaround for this. With the code here being as it is tho, it is ugly to hack into that flow
Maybe I can find the time to revisit this.
