@@EliteDynamite Welcome to Microsoft Q&A Forum, Thank you for posting your query here!
I understand that you are encountering the error Storage is not configured properly, Function scaling will be limited.
I also see that you have tried adding the storage account details in configuration -> app settings.
Every function app requires a storage account to operate since Function code files are stored on Azure Files shares on the function's main storage account. If that account is deleted, your functions won't work.
Please open the Azure Function App in the portal and go to the App Setting. Start by looking up your storage account name in your application settings. WEBSITE_CONTENTAZUREFILECONNECTIONSTRING should contain the name of your storage account as part of a connection string and WEBSITE_CONTENTSHARE has the name of the file share (if you are using consumption or premium plan). For more information, see App settings reference for Azure Functions.
Search for your storage account in the Azure portal to see whether it still exists. If it has been deleted, re-create the storage account and replace your storage connection strings. Also ensure that the Storage account isn't part of a VNET or have the Firewall enabled.
