Spectrum Notifications

We are a Pro User and have a Domain that is now using Spectrum.
The first 5GB are free each month and then it follows with 1Euro for each GB more.

Is their a possibility to setup notifications/warnings if the free quota is breached or something similar?

Kind Regards

You could set up a notification for Usage Based Billing.

It does allow you to set up notification for whatever amount of usage you want to be notified at.

We tried that. But the select field for Product only shows us “no option”.
Do we need to stetup something else before this step?
