Rate limit exceeded when publishing a single message

I’m getting “Rate limit exceeded, please wait and try again” for any and all messages pushed to webhooks in customers’ account. Same device, firmware and webhook configuration works when used in non-customer account. There are no restrictions configured on organization level (i.e. customers are allowed to use APIs etc).

Any suggestions?

I have a similar issue… About the half of the calls of a webhook, have a este limit issue (even having 1 per minute).
Any news?
