In Web AppBuilder, the hideLayers URL parameter does not work for layer IDs and multiple layers cannot be separated by commas.

1. To hide layers, the only option is to use the full layer name. Copying and pasting the layer name from the legend in Web AppBuilder is a good way to do this. When the full layer name is used, the URL parameter hides the layer correctly. Syntax: &hideLayers=<full layer name>. URL as configured: https://ess.maps.arcgis.com/apps/webappviewer/index.html?id=d2f4f0029b5a4f4a9cdb200cfc5476ff&hideLayers=UV_Polys%20-%20DRD_Artwork_test
2. To hide multiple layers, the workaround is to use either a semicolon or the characters %3B, as described in a similar bug for showLayers, BUG-000121304. Syntax: &hideLayers=<full layer name>;<full layer name> or &hideLayers=<full layer name>%3B<full layer name>. URL as configured with the use of the semicolon: https://ess.maps.arcgis.com/apps/webappviewer/index.html?id=d2f4f0029b5a4f4a9cdb200cfc5476ff&hideLayers=UV_Polys%20-%20DRD_Artwork_test;UV_Polys%20-%20polytest. URL as configured with the use of %3B: https://ess.maps.arcgis.com/apps/webappviewer/index.html?id=d2f4f0029b5a4f4a9cdb200cfc5476ff&hideLayers=UV_Polys%20-%20DRD_Artwork_test%3BUV_Polys%20-%20polytest
   1. Note: using the layer IDs still does not work with this option, as seen with this URL. https://ess.maps.arcgis.com/apps/webappviewer/index.html?id=d2f4f0029b5a4f4a9cdb200cfc5476ff&hideLayers=0%3B1
