We are aware of a known display error affecting nearly all Deco models on the market. A beta firmware release addressing this issue was made available about two weeks ago; however, your specific model was not included in that update.

I recommend responding to the post below to inform them that you are experiencing the same issue. Please include your Deco model as well as the firmware and hardware version in your response.

Additionally, you may consider opening a support ticket to report that you are encountering the same issue as others.
