Hi,
I'm encountering an issue where features in my layer don't render unless they're queried for. Unfortunately, this layer is secured and belongs to a third party, so demonstrating the issue is not something we can offer publicly, but we can provide credentials to ESRI developers that want to look into the issue. I've attached a video of the issue, and the repro project can be found here: https://github.com/AceCoderLaura/ArcGISRuntimeBugDemos. The bug is listed on the main menu as "Feature Not Rendered Bug"
Thanks.
