Hi team, Our app is going to upgrade the backend infrastructure which needs to inform an announcement to the users. It seems there is a limitation that doesn't allow a message related to the decommissioning put up on the App's home page. I have check some docs over internet but still not found any official one specify this topic. Can we just put the message as mentioned above or there is actually a limit which not allow to add it in? Thanks
