App not working but Works on Windows

Hello, I am Confuse about Why My App Is not working on Android or iPhone but Works on Windows. It is hard to Explain, So I showed what’s happening in the video.

Here Is code Block

Anyways I can fix this?

Never find… I fixed it. What I did was changed Local Storage to Real-Time DB. Thank you for helping me!

If Button58 is the Login button then it may be freezing because you are not saving a value to the “Local” key. There’s no block there so I assume it’s a null value.

If that’s not the Login button, then you either need to post a link to your project or more screenshots.
