We are planning on the release of Mobile v3.1.14 this coming week. This version includes improvements for Custom Exam, addition of 2 new signature types, a bug fix for Custom Vital signs, some UI/Color updates, and additional error checking for failed uploads. Additional details will follow with the release notes next week.
Also, after this release, for the users still on something prior to 3.1, we will be providing warnings to upgrade. At some point in the near future, an upgrade will be required.
