Could someone please verify this issue as I am sure it has only come up as of recent.
I am sure that up until December 2016 I was able to snap features in a WebApp regardless whether I was creating a new feature or editing an existing feature.
We edit features in this WebApp very often, I noticed this change occur after the December 2016 update to ArcGIS Online.
I haven't seen any mention of this as I assume it may be something that wasn't intended.
Once again, does anyone else have a WebApp they could try this on? I will try a few different configurations in the meantime. The same issue is occurring in the WebMap as well.
To avoid a simple question an answer, no changes were made between the day it was working and the day it stopped working!
I look forward to any input.
Well I have tested this just using the JS API (which WAB is built on) and you can not snap existing features to other existing features. I used this sample and then rolled the JS API version back all the way to 3.15 just to be sure that this did not work at some point in the past and it did not.
So I am unsure as to why to where seeing this ability when it was not supported in the JS API.
