Can’t Share my Calendar

Hello,

I’m having trouble sharing a calendar that I just created with my husband who also has an iPhone. Within the Apple Calendar app, i created a new calendar, and then I went back in by click the little i with a circle around it, for the info on the calendar, and clicked into “Add Person”. However, if I click on the + button to scroll through my contacts, I can’t add who i want to, a lot of my contacts are grayed out and I can only add random ones, I can’t see a pattern to which ones are not grayed out (ie, which ones I could add).

I tried making this calendar a public calendar, and then trying to add my husband, and that didn’t work. I made sure that we both had Calendar as our default calendar app, and we do. I tried doing this from her phone, and that doesn’t work (same issue).

I added him onto my iCloud plan, so we’re using family sharing iCloud plan, and that didn’t fix the issue.

Someone, PLEASE help me, I just want to have a shared calendar with my husband.

ANY help is soooo so appreciated.

Thanks in advance.
