iCloud calendar on iphone
When I open my calendar, then select "calendars" at botton of screen, under iCloud calendar it says "Verify Account Information" and "Unable to update account due to missing information." If I click on "Verify Account Information" nothing happens. My family iCloud calendar on my iphone that I share with my husband is not syncing. When I create a new event it does not show up on his phone and vice versa. Weird thing is that it does sync on my same family iCloud calendar on my iPad just not my iPhone. Any guidance on how to fix?
iPad, iPadOS 17
