On November 13th, 2018 between 2:29 PM (PT) and 5:39 PM (PT) customers were unable to delete private channels if they were previously converted from public channels.
We made a change at 2:29 PM (PT) that affected how we check for token types and scopes in our API in relation to private channels. This introduced a bug that prevented customers from deleting these private channels. The change was reverted at 5:39 PM (PT).
To those affected, we are truly sorry for interrupting your day and are working hard to make sure this doesn't happen again.
If you notice any further issues with deleting channels please do let us know at firstname.lastname@example.org.
