We're pleased to report we've fixed this issue, and all customers should be able to add other members to channels using the 'Add people' or 'Add people to channel' buttons once again. We're sorry for any disruption caused in the meantime.

Some of our customers are unable to add members to channels through the 'Add people' or 'Add people to channel' buttons. This seems to be affecting our Enterprise Grid customers specifically. We're currently investigating but in the meantime, people can add members to a channel using the /invite command. If you are seeing any issues with this feature currently, please write in to email@example.com so we can look into this further.
