I have tried to click on the save button and also the other buttons but I am not able to do it. I have run the case on Android version 7.0 (Moto G4 Plus) and version 8.1 (Samsung On6). When I run it on version 7.1.1 (Lenovo K8 plus), the code is able to run automatically without any error. Can someone provide any solution to it as I am stuck on this for a couple of days? Also, have applied all types of the wait.
