Attention views for SharePoint libraries that are missing required metadata are a new Office 365 feature. You’ll begin seeing this feature in the coming weeks.
How does this affect me?
Attention views, which were announced at Ignite 2017, aggregate files that require custom metadata into actionable screens that enable bulk management and updates.
We’ll be gradually rolling this out to First Release customers in early October, and the rollout will be completed by the end of November.
What do I need to do to prepare for this change?
