Slow and Buggy on iPad and iPhone after IOS 10 Update – Microsoft Outlook Review

Since launch this was my favorite mail and calendar app on IOS devices. Unfortunately after 24 hours of using Outlook on iPad and iPhone 6 on an IOS 10 device, Outlook has become nearly unusable. First, it's really slow when deleting emails, or when switching between Focused and Other mailboxes. Secondly, at random times, I see my emails duplicated and sometimes it feels that emails disappear. Hope Microsoft gets on top of this soon. Contacted support and they went through the normal restart the app, reset the email accounts, uninstall Apple Watch app, but no impact to the above issues.
