Currently Jira Cloud on ipad and macOS is crippled by not being able to view more than one issue or filter at a time. It makes it basically unusable, especially on macOS, for anyone that is using Jira for serious work. I like the improved performance of the native app and I can understand not everything being implemented yet. Not being able to open multiple issues, filters, boards and other views in tabs is in my opinion the most important downside.
