If you have any problems with CalenGoo there are a couple of things you can try to fix them:
- Reboot the device: Hold the upper button of the device until a red slider appears and use it to turn it off. Afterward turn it on and see if it helped.
- Reload all calendars: By using “Settings”, “Reset calendars” you can erase all events and calendars and re-download everything from Google. This helps to fix most sync issues.
- Run the sync with “Settings”, “Debug Tools”, “Debug Sync”. It will show you exactly which changes and events are downloaded. It displays the modification date and time of every downloaded event. Syncing means to download all changes that have a modification date/time that is newer than the date/time of the last sync.
