Error in UseMethod("html_table")

Error in UseMethod("html_table") :
no applicable method for 'html_table' applied to an object of class "xml_missing"

are you a registered user of the service ? did you do the validation step ?

I got curious, and I wonder if your issue relates to this :
The access to the ESS data is changing · Issue #56 · ropensci/essurvey (github.com)

Yes, I have already registered on the ESS website ! For the validation, I did not receive a message in my inbox!!
