When I install my app on my phone and get to the main screen when I click a button to open another screen the screen opens for a few seconds then closes and goes back to the main screen. this happens no matter what screen I open. Help!
you probably have a clock still running on Screen1?
It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.
To get an image of your blocks, right click in the Blocks Editor and select “Download Blocks as Image”. You might want to use an image editor to crop etc. if required. Then post it here in the community.
