Preview and Publish is always disabled

For me, in web browser IDE and native environment, the buttons for Preview and Publish is always disabled (dimmed). Is that a bug or must I do something special to enable these two buttons? I work in Mac Studio M1 Max 2022 with Safari 16.6 and Chrome 125.0.6422.142 (Officiell version) (arm64), MacOS Ventura 13.5.1.Create DP1.

I guess this is “not implemented yet”. But on top of that what will be the difference between “Preview” and “Run”? Will Preview be the way to test on-device if I develop a mobile app?

Thank you for the report @BoL59 !

As @Hliljegren mentioned, the Preview and Publish features are not yet available, which is why they are currently disabled. These are key functionalities we are actively working on, so please stay tuned!

The Preview feature will allow testing on multiple devices, functioning similarly to the test button in the Classic IDE, though with some differences.
