We have lots of sub-accounts using WhatsApp, and every now and then Meta blocks WhatsApp from being used so we can no longer use it on the sub-account. This causes automated messages not to be sent, and we are not notified that the WA has been disabled.

The only way to check is to manually go in to each sub account and check if the WhatsApp account is still live.

It would be great to be notified of this! Or have a trigger for WA error messages, where we could create an automation triggering on the error message 'business account is locked' etc.
