The chooseAsync functions displays "Play with friends" dialog, but friends don't receive any notification or invite to join the game.
Could you please post an working example (for Construct 3) of how to use updateAsync to actually send an invite message to a friend? Just a simple text like "Can you beat my score?" and a game logo.
I'm guessing it should be something like "FBInstant.context.chooseAsync() .then(FBInstant.updateAsync.....", but I've spent several hours and couldn't get it working..
Also, how do you get a Base64 string from a sprite in Construct3?
Edit: Never mind, I did it!
