Here is the output of terraform plan

Terraform will perform the following actions:

Plan: 1 to add, 0 to change, 1 to destroy.

Expected Behaviour

Adding an additional channel should not require deleting the contact profile. The API has a way to update the contact profile. And, from the Azure portal I am able to add a new channel without deleting the contact profile.

Actual Behaviour

The terraform plan showed that it needed to delete the contact profile before it could add a channel.

Steps to Reproduce

1. terraform plan

Terraform needing to delete the contact profile is an issue, because you cannot delete a contact profile if you have ever used that profile to conduct a Contact in the past (unless you also delete all of those past Contact objects)

Hi @rmelick-muon, thanks for reporting.

I have opened a PR for this(https://github.com/hashicorp/terraform-provider-azurerm/pull/25129), once it merged & released it should be fixed.

Thanks

Thanks @ziyeqf! Looking forward to testing once it's released :)
