Using Garmin Connect (Android) to edit Activity data screens on FR255 (Latest software on both devices as of 18/01/24). If a factory default data screen is edited to increase the number of elements to 8 it disappears from the edit page selection list. It does still appear in the list of pages which can be deleted/moved. So once changed to 8 elements it can only be edited on the watch. It appears in the deletion selection list with no name. If there is more than one page with 8 elements they all appear the same with no name. Looks like a bug in Android Garmin Connect. Possibly the auto name generation routine which may overrun when there are a large number of data elements?
