Since version 1.75.8, Heptabase has hidden the Deactivate cloud sync and Activate cloud sync buttons.
Previously disabled sync and want to reactivate it: Contact support so we can enable reactivation for your account.
Sync is active and you want to deactivate it: This is no longer supported.
Switching sync is prone to data errors in the current Heptabase architecture, so we are gradually phasing out support for this feature.
