I just published a feature service to ArcGIS Online and added it to my web map. It's got two point layers in it, and when I added it to my web map, it was working just fine. I saved the map and exited it, then went into the feature service properties to add a few fields and coded values. When I opened the web map again, I noticed that only one of the point layers in my feature service was in the map. I tried re-adding it, but it would only show one layer.
I decided to try republishing the feature service, which worked for the first time when I had the web map open, but when I saved and re-opened it, the other layer disappeared again.
Is this because I was editing the fields of one of the layers and not the other one? Is there any way for me to add the other layer back into the feature service from the web app?
