Hey So I have followed the following tutorial for android to integrate heyzap mediation: https://www.buildbox.com/forum/index.php?threads/android-heyzap-mediation-tutorial.4037/#post-24463 The problem I have is that when I launch the app on an android phone, the button does not appear at all. I have tested multiple times for 5 days and nothing happens. If you have a solution, please share. There are many threads on buildbox regarding this issue, and none were resolved. Thank you.
