"Open Level" only works in Editor - Not in Standalone or packaged game

@Elou44 I’ve tried the cook on the fly option but it never ends compiling, since it needs a virtual machine (like you I try to launch on the phone via the “Launch” button)
Having set all my maps in the project asset manager doesn’t work, same for including maps in the package settings.
No matter what I do, “Open level” never opens anything. I’ll have to put the apk on the store in order to try since apparently the behavior is different, but I really would like to launch on the phone (I don’t have internet on the phone, so each time uploading to the store and waiting for somebody to try is far away from ideal).
Maybe there is an other way to try on the phone without download from store or via “launch”, but I haven’t found yet.
