Hi Guy, need opinion on store variable. maybe my block is wrong somewhere else. It worked on ios but in android does not display anything. screen1 ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/f/e/fe664ed18b076bcc8fa69f5dec4f2f3840984d6c.png) screen2 ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/b/2/b2a696454f34baa21b474deedd55a0897ccb2e5b.png) ---

The start and open events have a variety of irregularities between platforms and navigators. To test the issue, try using a button on screen 2 and see if you can populate the label. To understand when start and open events occur, I have found it helpful to use the SPEAK/SAY blocks. You will definitely discover some interesting behaviors. Happy Thunking. ---

**UPDATE:** I replicated the problem on my android device. If there is a loading\_icon on the screen, the open event does not occur. Do you have a loading\_icon? Visible or not Visible does not matter. Here is a sample. it works on Live Preview Web, but not on android. ☹ > **[Thunkable](https://x.thunkable.com/copy/3f7427cfff914fd36ff8cdd40bc4e096)** ---

This appears to be a new bug, but hopefully it will be resolved soon. In the meantime, you may need to consider these options: 1. Use the start even instead of open event 2. Remove loading icon ---
