Slack app doesn't work

I configured Sentry on Slack. It worked for 1 month, but now It doesn’t receive notification on my channel.

I delete configuration and recreate all from scrach but It doen’t work.

Can you help me?

Thanks,
Salvatore

I’m having the same issue. Also, it seems I also stopped receiving email notifications.

EDIT: Seems like both e-mail and Slack notifications are back up and running.
