The Ticker Message Item (pictured) has a character limit of 2500. Any characters following the 2500th character of a Message will not appear on your Ticker.
You can work around this character limit by creating more than one Message Item in a Ticker Playlist and arranging them in order.
I have a Message that I want to display. I’ve noticed that the message is being cut off, and I’ve estimated that the amount of character in the message is 3200. I can correct this by creating two Message Items, which I’ve named Message Part 1 and Message Part 2. Message Part 1 contains the first 2500 characters, Message Part 2 contains the remaining 700 characters. I’m scheduled them to play in order, so my message will play through the Ticker without interruption.
