1) Verify CycleSync has calendar permission in your system settings. 2) Verify the calendar you want to see is enabled in CycleSync → Settings → Calendar. 3) Force-quit and re-open the app. 4) If the issue persists, email us with your device model and OS version.
Check three places: (1) CycleSync → Settings → Notifications — make sure the types you want are enabled. (2) iOS Settings → CycleSync → Notifications, or Android Settings → Apps → CycleSync → Notifications. (3) Your system Focus / Do Not Disturb mode, which can suppress scheduled notifications.
Email support@cyclesync.app with a description, screenshots if possible, your device model, OS version, and CycleSync version (visible on the Profile screen). Or use the in-app Send Feedback option on the Profile screen.
