Source View Limits

Source view limits work on a slot-based system:

  • Basic: 5 slots available
  • Lite: 30 slots available
  • Pro: Unlimited slots

Note: You have a fixed number of slots. When you delete a source view, that slot becomes available again. Views are synced across all your devices via Firestore.
