Then unfortunately I think this is just like I assumed that the blocks return the last manually set value and not the last value of user interaction 
This would definitely be something that need improvement - also for the webview since currently “get URL” does not return the current URL but rather the last one you set…
Does anybody know if there might be a workaround by working with the objects block just like there is a workaround to be able to place a marker at all?
best, Chris
