I want to create a Time Slider simply using Map Notes and show the points over time. All the instructions I can see are for using a Time Slider with data from CSV files and applying this to a map layer.
But I just want to mark points and show more points emerging over time.
Do I need to have a "time enabled" map or layer to do this? I am using the Ordnance Survey Ireland Base Map Eire, but it doesn't seem to have time features. Can I apply a Media app layer over this even if it isn't time enabled or does the base map have to be time enabled?
Can anyone help with this? I would be very grateful as I am at my wits end with YouTube tutorials that do not apply to my case. I am using the most recent version of ArcGIS Online.
