Tips of the day: test the application in release mode often, it will avoid you some surprise.

[Rok Oblak]

What kind of surprise did you have?

[Michael Paus]

The most common surprise is that your release build just fails because ProGuard can’t cope with it and you’l have to find and add extra rules to make it work again.

I see, but you are talking about desktop?
On web I had no surprises yet apart from a external lib linking error which is being fixed due Kotlin 2.0.20

On Js target got runtime error cause of undefined property when run production build. Went so far from last prod run. Now trying to find the reason.

@PHondogo is it the same as this issue?

Clean build fixes it (for now, 2.0.20 will fix it)

[PHondogo]

Unfortunately not.
