The node Show External Login UI is called in the event graph of my game instance. To help debugging. I’ve added a button on the main screen that triggers an event in the game instance. The event launches Show External Login UI that now only tries to connect. I thought about what you said: the login node is in the event graph of the game instance. I checked all screenshots from the prelaunch reports. It works every time: sdk 30, 31 and 33. I don’t know what the difference between the google test environments and mine.
About the sdk version target: it seems that google will refute games which doesn’t target sdk 34 at the end of august or september.
About the log: yes, i downloaded the source code, activated the log in shipped builds and build the project. I get the log with when my phone is plugged. I followed the epic tutorial.
Do you make any progress on your problem?
