I came to revisit this.
@amc4x4 has the right solution above. That worked on the latest version for me.
We are also seeing this same issue –
Error: Authentication failed. Please reset settings and try again (Error: access_token is invalid, unknown, or malformed: Invalid authentication credential value(s) in Authorization header parsed from http headers)
Has anyone found a fix yet? As far as we can tell the connect app is set up correctly and has the correct scopes.
@justinhandley I’d love to try out your updated version of this plugin. Did you ever have any luck contacting the author?
