iOS Boxer 4.7.1
When “Whitelist” is selected under the Sharing section of the DLP settings for Boxer, users are unable to attach images form their Photo Library. Only when “Unrestricted” are users able to attach images from their Photo Library.
Note: This is only occurring for devices running iOS 11 and Boxer 4.7.1.
Users can copy and paste photos from Photos and paste them inline in the email if this setting has been enabled. Additionally, users can attach files using the new iOS Files application by selecting Browser when attaching during compose.
This issue has been resolved in VMware Boxer 4.7.2.
