Yes, I have 1 popup translated in 2 languages. In dashboard it looks like this: https://drive.google.com/file/d/1eK2zrvrHh3CG782cYtOh29uYTDjPnEYI/view?usp=sharing.
I tried to make it once more, from beginning, but the result is still the same. When I turn on just English it works, but when both, English and Polish are turned on, only the Polish one is showing. Test mode is disabled.
