I found a bug in the WebApps app home screen shortcut not functioning

Expected behavior

habits after we open the web we want to save the page Shortcut on the homescreen to make it easier for us to open the web again, but after I do the screen shortcut turns out the feature is not working I expect this feature can be used

Actual behavior

after I open the web in DuckDuckgo search I search the facebook web after the open web I want to make it easy to open it again by saving to the homescreen ShortCut, after I go home to the main screen but the feature says error

How to reproduce

• write a page for example Facebook

• after the Web is open then choose to save the Home Screen Shortcut

• Browser: WebApps Version 2.16
