Yesterday my app worked fine, now list viewers aren’t working. Did something change? ---

Hi @Colby_Frechette, Thanks for your question. Can you create a minimum working example and share it here so we can take a closer look? Also, when you’re sending this can you also clarify whether this affects live testing or installing and if you are using anrdoid or iOS. Thanks. ---

It affects both as far as I can tell. I did live testing on iOS and downloaded it and tested it on BlueStacks, neither of which work. I made a minimum, non-working example. [Here](https://x.thunkable.com/copy/48784149eaab61c9c730d0122c3ab350) ---

@domhnallohanlon I’ve done some more testing. It seems as though setting objects to visible is the source of the crashing, not the List Viewers. ---

Thanks Colby - I’ve verified this on my end too and submitted a bug report. As a work around for the moment, I’d recommend setting the height of the components you wish to hide to 0. Apologies for the inconvenience. I’ll follow up here when we get a fix for this. Thanks! 😄 ---

If can help this is the error on android live test ![Screenshot_20190410-184834_1](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/1/c/1c543036060c114e38e958836a1f53ea2abfe20f.jpeg) ---

Sorry for this ☹ We are actively working on this problem and if all goes well should have a fix out sometime later today. -Mark ---

Thanks for your help identifying the issue, we’ve fixed the bug. You may need to open the blocks editor in your project and move a block so that the code refreshes properly. ---

I have made an app with a loading screen at the beginning and every time I launch it on thunkable X it crashes within 5 seconds. This has only been a problem since the recent update. Any fixes yet? ---

Hi @Leon_Cummins, welcome to the Thunkable community. 👋 In the absence of any other details, I’m going to guess this is the issue that’s affecting your project?

Awesome, I’m glad you guys were able to fix the problem. Just a shot in the dark, can I get a cool free Thunkable t-shirt or something for helping? @domhnallohanlon @Mark @paulmw ---

@domhnallohanlon @Mark @paulmw The List Viewer problem is happening again. It still crashes the app sometimes. I will try further testing to see if I can find out what exactly causes it. ---

Thanks, @Colby_Frechette! If you can create a small example project that shows the problem, that would be ideal. -Mark ---
