Slack links fail for digital lounges

On the Digital lounges page there are links such as https://slack.com/app_redirect?channel=C03HCBT0N58

When I click one I end up on a random Slack channel I've been a member of for a long time, with a failure, eg: https://haiku-community.slack.com/app_redirect?channel=C03HCBT0N58 and message like this.

There’s been a glitch…

We’re not quite sure what went wrong. You can go back, or try looking on our Help Center if you need a hand.

Fixed it.

I logged into Slack using the same email address as my Apple ID (which interestingly mapped to an email address to which it is forwarded, in a related domain).

Down the bottom of the page was a section with two outstanding invites.

For some reason, I had not received any emails alerting me to these invites.
