the release notes are somewhat vague and I don’t use iOS in my real life, so I need to ask what I’m doing wrong even though I feel a bit like an luddite even asking ...

Release 14 says iOS multi select is available for Photo Library now along with access to the Attachment card to add details.  Release 11 says that iOS multi select is done with a ‘select’ button

in app, whether I select a pic or long press to get the select button, I go to the Attachment card - which then saves and takes me to the attachment screen. 

How do I select more than one pic in iOS mobile?
