I have a Slack account through my organization. I created a Slack channel and invited 2 guests outside my organization to join my channel. They used to be able to use the Slack channel for 2 weeks, but since today, the 2 guests can't access the channel anymore.

The guests don't see any error message when trying to access the channel:
I can't see any error because it redirects me to other slack channels that I have.
