Why won't multitasking work on my iPad?

Only select models of the iPad running iOS 9.0 support Slide Over, Split View, and Picture in Picture. You see a list of what devices support what multitasking features here. Third-party apps also have to be updated with iOS 9 multitasking support for the features to work.

Here are a few popular apps that have been updated with multitasking support:

• Pixelmator
• Microsoft Office: OneNote, Word, Excel, PowerPoint and Outlook
• Vimeo
• Procreate
• Chrome
