Creating Function Apps in an existing Resource Group

In some cases, when trying to create a Dynamic Function App, you may receive the following error:

The Dynamic pricing tier is not allowed in this resource group

This can happen in the following situation:

• you're creating the Function App in an existing resource group
• this resource group already contains regular (i.e. non-Dynamic) Web Apps in the same region that you're trying to create the Function App in
• the scale unit that those non-Dynamic resources are in does not yet support Dynamic

When that happens, your best bet is to create a new resource group to avoid the situation. Eventually, all scale units will support Dynamic, and this condition will no longer occur.
