Acceptance Criteria

• When user clicks “deactivate” for mod with “sync across devices” checked on, show the model defined here, see Ben’s recent PR around this: [When user clicks “deactivate” for mod with “sync across devices” checked on, show a modal:](https://www.notion.so/When-user-clicks-deactivate-for-mod-with-sync-across-devices-checked-on-show-a-modal-09b293bc46034503bc99b3c82580c10d?pvs=21)
  • Only do if the mod-personal-sync feature flag is set, use FeatureFlags enum
• When you’re reactivating a mod that is part of a team deployment (e.g. because you’re a dev that’s doing development work on that mod), disable the “sync across devices” checkbox with the following message (or something similar): “Can’t sync a mod that’s part of a team deployment”
  • Only do if the mod-personal-sync feature flag is set, use FeatureFlags enum
  • On re-activation, keep the existing behavior of removing the _deployment metadata
  • The background updater has logic to NOT activate deployments for which a non-restricted user has a more recent version active
