> [@Events Not Working](https://community.thunkable.com/t/button-not-pressing/1495834): > > Hi thunkable team. This has been a major issue for me since the past ½ hour or so. When i live preview using either my computer or phone and click on button, nothing happens and i can see only button pressed on the console. Though in the blocks section i have navigate to another screen block. Is this happening only for me or is it for everyone. I am not able to test any of my apps. NOTE :- The live preview doesnt work while this [image] button on the projects page makes the project work. I … ---

Same here. I came to realise, app containing Web\_APIs will crash upon testing. Must have been the updates. My apps were working the day before ---

ok, i found out when the crash occurrs spending few hours and by replaying everything i did one by one… it seems to be the collapse-cleanup feature… the app is working first… an then i **collapsed** all my blocks in all screens…and clicked **cleanup** -blocks… its after that when i visit one screen app crashes… seems to be a problem with **collapse** -blocks or **cleanup** -blocks feature… @wei @domhnallohanlon is the order of blocks from top to bottom of any significance?.. ---

It seems the crash have very broad reasons. Buttons, Invisible blocks, Web\_API, and now clean-up blocks… what else.? ---
