I use the Jira Cloud app on a Samsung Galaxy S9 running Android 10 and an iPod Touch (7th Generation) running iOS 14.3
On the Android I can upload multiple photos at once to a ticket by selecting "add file" from the paperclip icon on the top and long pressing a photo and then selecting multiple photos.
Following similar steps, I am unable to figure out how to upload multiple photos at once on the iPod. Anyone have any suggestions?
