As my Classic project was almost ready to be published, Thunkable decided Classic was going to be shutdown. Converting to X is an option, but that system is proprietary, what happens if Thunkable decides they stop their business? 2 yrs effort down the drain, because there is no source code available that can be transferred elsewhere. or is there (or will there be) a way to safeguard my work, like in Classic with .AIA files?
Classic is different to Cross.
Therefore,their system may not same,there are no extension for Thunkable X.If your app involves a lot of functiona which made with extension.It is properly couldn’t save your project when you want to transfer Cross.
You should move the project to kodular: https://www.kodular.io/
(Before moving, you need to delete the components that Thunkable created)
