We've incorporated navbar UI element within headers of multiple pages in our Appery project (Ranzo_Diggs, shared with Appery). The behavior is as expected when tested in browser and on iOS. However, after multiple clicks on the navbar buttons, the button color start producing shadows in addition to active (blue) and inactive(white) colors (see attached screenshot) when tested on Android device. What is going wrong here?
Secondly, we notice that there is 3-5 second response delay on responsiveness of button click. I would think this would make launch of any decent app on Google Play impossible. Can you elaborate what is the reason for this delay and suggest measures to improve it?
