I have attached screen shots of the app preview on my Samsung S22 and Thunkable. The formatting is not the same. Why? ![Screenshot_20230303_092802_Gallery](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/b/7/b71292a54b44a78eb0a7fab7ecb91e9cd93bb4c9.jpeg) ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/a/e/ae36494fc0d5c885952a3615489e15c6e49a29d6.png) ---

I solved my issue by reading help. I had a screen load block that did not wok properly on the phone. Removed that block and things are working correctly. ---
