i have implemented firebase push notification in my project with payload json, I have done all the configurations and now when i click on the notification, it works sometimes perfectly but sometimes the redirection just doesn't work, let's say if i click the notification 10 times, it redirects to the desired page for 4 times and rest 6 times, its taking me to home screen. I am sharing my code below.

return true;
