Hi @AndreaConio   We experienced an outage that prevented our customers (including ourselves for a time) from replying to conversations, re-assigning conversations and closing conversations, among other things

You should now be able to reply to, assign and create new conversations without issue - our engineers have shipped a fix for this. You can keep an eye on our Status Page for updates on this.

Apologies for any inconvenience caused by this outage - if you wrote to us via the Messenger we will be in touch with you ASAP
