Connecting a calendar to Keeper.sh now starts a sync straight away. Events begin arriving while you are still on the page, so you can confirm the setup works, and a mistake in your mapping shows up immediately.
Before this release, nothing happened until the next scheduled run.
The same applies when you change what gets copied. Adjusting which calendars feed a destination requests a sync instead of waiting for the schedule, so you can check the change right away.
An event has not arrived in the other calendar covers what to check when a copy is missing.
