vCards with multiple contacts any more.

iPhone will not import vCard file with multiple contacts.

Back in Sept 2021, I had built a vCard with my workmates and we were able to open the file on our iPhones (as an attachment in email or saved under Files locally or iCloud drive) and we would be prompted to either import everyone in the file or it would show the individuals and we could select which ones we wanted to import.

Since my team has changed, I tried to prepare a new file. Not only does the newly generated file not work, but the old files from 2021 also do not work. But they worked in 2021.

I had been using vCard version 3.0 format. I have tried version 4.0, but no difference.
