Hmm, I thought maybe we had a ticket for this in our issue tracker, but I couldn’t find one. @sven is the man when it comes to push notifications. @sven, can you provide some input here?
Currently there is no way from inside Defold to cancel notifications that has been displayed (you should be able to cancel any pending notifications with push.cancel however). But as you pointed out, if other games usually clear this list if when the game is started, we should look into having similar functionality. I’m adding an issue for this: DEF-2501
