For me same thing… i couldnt work on my project all day…
In the best case scenario, im working on blind, cause i cant see anymore changes to ThunkableLive mobile app. There it shows old stuffs i did long time ago. Its like server dont have connection with mobile LiveView anymore…
I think that the problems with Thunkable server are more seriouse that i thought 
More problems happened to me in the last hour… Even if i make from the scratch a new screen in my project, with a simple container with an image, if i try to preview on mobile or even in Web Live Preview here, on Thunkable Website, it shows deformated things, and so on…
Its like server has its own conscience and its ALIVE, doing the things the way it likes 
I hope that problems will be fixed soon… I started to like very much this kind of “coding” in the last 10 days…
This is on my web pre3view… the things looking even worst on mobile app…
And believe me, i know how to arange items on screen, with containers and so on…
