3 commentsThe only information they give out is "we were not hacked, we know what the priblem is but we won't tell you" Why not tell us the current state of the investigation? They obviously didn't have a good ci/cd process for deploying changes to channel files and they should at the very least describe the release process, as far as they know how it, for channel updates are tested before release (if at all).
