iOS calendar doesn't search properly
Hi-
For several months I've had a problem searching my calendar on an iPhone X and iPad mini.
When I name an event, say as "tom" when I search on Tom it returns most but not all of the items named tom. I've opened and closed the calendar, rebooted both devices....no love. The calendar works fine searching on my iMac and in iCloud but not on either iOS devices, making them unreliable for my main scheduler.
Any troubleshooting tips or ideas most welcome.
thanks,
Marianne
