I have several maps that have a mixture of editable layers and non-editable layers. I have tested in both AGOL and Portal. In Collector classic everything works perfectly. In the new collector app in recent weeks the editable feature layers no longer show up. Not editable layers appear just fine. Any ideas?
Hi Bard - Do you have an example map where this is happening that you could share with us? The easiest way is to create a group, share the map and layers with that group, and invite user Collector4ArcGIS to it.
