Hi,
This should not happen. The core browser engine is completely asynchronous (unless you explicitly use one of the blocking functions). So loading a web page should not block the UI. If you continue to have problems, please try to isolate the problem into a test project and send the test project to us. Once we have that we will investigate further. See here for more details on how to send test project to us:
https://www.essentialobjects.com/forum/test_project.aspxYou can not use Task.Run to send the loading to background thread. The WebView is thread specific, which means most of its methods can not be called in a different thread. So calling it in background thread will only make matter worse.
Thanks!
