I've never used Slack so I can't help with the rest of your question.Just to say, as someone who does use Slack and has coded an OAUTH integration at work, that this is not a Slack issue, it is an OAUTH protocol issue. There is likely a bug (hard to say what from here) in the token exchange and groups.io is not receiving/recognizing/validating/etc. a token properly.
There's nothing anyone on this list can do about this, the ball is entirely in Mark's court and the previous suggestions of writing to the support email address is the only viable route forward.
