~ resource "azurerm_function_app_flex_consumption" "test-function" {
                          id                                             = "/subscriptions/***/resourceGroups/testfunction/providers/Microsoft.Web/sites/testfunction"

                          }
                          # (29 unchanged attributes hidden)

                          # (2 unchanged blocks hidden)
                      }

Expected Behaviour

Memory on the function app should change from 2048 to 4096 successfully

Actual Behaviour

Terraform completes successfully however the memory change does not actually get reflected in the function app flex consumption

Steps to Reproduce

1. Set instance_memory_in_mb to 2048
2. Run terraform apply to Create a new function app
3. change instance_memory_in_mb to 4096
4. run terraform apply to update existing function app

I was able to reproduce this issue. The instance_memory_in_mb does not seeem to change the memory size of the app. @xiaxyi FYI.
