Adding another calendar is blocked by a plan limit
Created August 14, 2026
Free covers 2 linked accounts, 3 connections and 1 shareable link. Here is what each of those counts, and how to rearrange a setup so it fits before paying for Pro.
Guides
Fixes for calendar sync, each one starting from what you can see. Events that read Busy, copies that have not turned up, the same meeting twice, a subscribed link that lags behind.
Copied events arrive without their titles
Created August 14, 2026
Copies carry the name of the calendar they came from, and a shared link reads Busy. Both are privacy defaults, and each is changed in a different place.
An event has not arrived in the other calendar
Created August 14, 2026
You made an event and the other calendar is still empty. Work through the wait, the direction of the connection, the date range, and the calendar you are actually looking at.
Copied events have disappeared from the other calendar
Created August 14, 2026
Copies that were there yesterday and are gone today have a short list of causes, and a narrowed date range is the most common of them.
The same event appears twice in one calendar
Created August 14, 2026
Seeing one meeting twice has three usual causes. A two-way setup you did not mean to build, another sync tool still running, or the same calendar reaching you by two routes.
A subscribed calendar is showing out-of-date events
Created August 14, 2026
Your link is current but the app showing it is hours behind. A subscribed calendar refreshes when the app decides to, and some apps wait hours between reads.
