I just tried device.openapp("com.imdb.mobile") as an example - nothing happened. Generally actions in remote.lua for the client like device.toast("...") or device.keyboard() are working. When I inspect server log:

"attempt to call field 'OpenApp' (a nil value)"

Is it true (according to first post) that OpenApp is implemented? I also didn't see anything in the documentation...

Thank you!
