Nextcloud with Replicas on Azure Kubernetes - Failing to Mount Azure Files ReadWriteMany Volume

I'm trying to deploy Nextcloud w/HPA (replicas - horizontal scaling) on Azure Kubernetes with the official Nextcloud Helm chart and a ReadWriteMany volume created following these official instructions, but the volume never mounts, get this (or some version thereof) error:

Here is my PersistentVolume yaml:

apiVersion: v1
kind: PersistentVolume
metadata:
  name: nextcloud-rwx
  namespace: nextcloud
spec:
  capacity:
    storage: 32Gi
  accessModes:
    - ReadWriteMany
  azureFile:
    secretName: azure-secret
    shareName: aksshare
    readOnly: false
  mountOptions:
  - dir_mode=0777
  - file_mode=0777
  - gid=33
  - mfsymlinks

PersistentVolumeClaim yaml:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: nextcloud-rwx
  namespace: nextcloud
spec:
  accessModes:
    - ReadWriteMany
  storageClassName: ""
  resources:
    requests:
      storage: 32Gi

I've also tried changing uid and gid to 0, 1000, etc, and get an even more egregious permission denied message because it doesn't "match the fsgroup(33)" (hence why I tried with gid=33).

Any ideas would be greatly appreciated! Thank you for your time.
