After pre-releasing its upcoming refresh of its Business Manager at the Pinterest Presents event in September last year, Pinterest finally rolls out its new changes in the app, making it more manageable for you when dealing with your Pin campaigns in collaboration with other staff.
Get access to new features in Business Manager

Core updates
New collaboration tools to help better workflow across your organization
Ability to re-use existing ad audiences between ad accounts
New Asset Groups to have more fine-grained audience targeting
Additional security in the network which allows staff to be forced to implement 2FA
A main focal point as discussed above, is around collaboration, and the ability to allow multiple participants to be able to participate in a Pin campaign. Which not only can help within internal projects, but also when working with influencers by giving you further means of integrating content in-stream.

There are some pretty useful updates here, and it may make things a lot easier for you in your Pin creation process.

Pinterest Business Manager is available to anyone with a Business profile in the app.
