On my LG L70 the Outlook application will drop Holidays and Birthdays, then I have to manually set the Holidays and Birthdays back on. Open Outlook app, click on Calendar, click on the three dots in the top right corner, select Calendar Settings, click the switch to turn on US Holidays and Birthday for my Contacts, then go back to email then back to Calendar to refresh the screen, and the Holiday and Birthdays show. After a few days the Holidays and Birthdays drop, disappear, then I have to go through the manual processes again.
What setting am I missing to stop Holidays and Birthdays disappearing?
