We’ve re-deployed the fix described below after having fixed an issue that we originally discovered with it
The just-now-deployed version of Thunkable ✕ fixes most of the issues that people have been having with variables, lists and objects. Note that in order to have the fix take effect you will need to force quit and restart our Thunkable Live app, as well as refresh the browser page where you are running x.thunkable.com.
There will still be a (hopefully) small number of apps with issues. Those will be the cases where the app modifies a list or object that is itself within another object or list.
