Starting February 10, 2019, Rainbow will no longer be supporting Android versions 4.1 to 4.4. After that date, your Rainbow application may not perform as expected on these versions.
Rainbow always strives to support the platforms most requested and used by our customers, and will periodically update our supported platform list to accommodate customer needs. In order to limit any disruptions in your support strategy we recommend making the update as soon as possible.
Why is Rainbow removing this?
The increasing gap between these old versions and other limits our technology options and hinders our ability to continue to deliver the reliability and functionality you expect.
Thanks for your understanding,
Your Rainbow Customer Care Team
