When the connection breaks, you’ll notice gaps in your daily agenda, duplicate entries, or events that appear several hours off. The inconsistency can make scheduling meetings feel risky and may cause you to double‑book or miss important reminders. These symptoms are usually the first clue that the two services are not truly communicating.
Behind the symptoms lie three technical culprits: iCloud’s private calendar URL that changes without notice, Google Calendar’s limited refresh frequency, and outdated device permissions that prevent the link from being refreshed. Each factor operates silently, so users rarely see a clear error message and assume the problem is their own fault.
