Hi Zara. Thanks for the feedback. What I am trying to do is create a dashboard with a point layer that with refresh and two tables that will also refresh. In addition to this I want one "back ground" polygon layer (made from an uploaded shapefile) with labels configured.
This morning I configured labels for the polygon in map viewer and then opened it up in map viewer classic. To my surprise the labels persisted in classic! Is this a supported work flow?
Great thanks! I was able to set my table refresh in the classic then do the label is the new viewer. I checked the json for the map when I was done and the refresh interval was retained. So, it looks like I can have the best of both worlds.
I encountered the same problem and came across this thread. Indeed the option to set interval is missing for tables in the interface, but you can set it using the ArcGIS Online Assistant. It is explained in this thread for layers, but it works the same for tables.
Using that thread to explain the AGO-Assistant, use the following format to add a refresh to a table for the new map viewer.
1) Locate the tables in the JSON.
2) Add a comma behind the "itemid" item as pointed out with the up vertical arrow below.
3) Enter a new line and add "refreshInterval":0.1 as shown below with the horizontal arrow below.
