A few things to know
A shared target includes the title, exact instant and selected zone. Local saves stay in this browser. Completion follows the 60-second late rule.
IANA zones follow date-specific daylight saving rules. Repeated times need a first/second choice; skipped local times are rejected.
On return, targets up to 60 seconds late ring once. Older targets are marked missed. Sound may need permission again.
Check tab mute, device volume and Bluetooth output. Notifications are not required.
