Most of the time these pop ups can all be "translated" when you open the Gacha screen. Since there are so many tabs and there is one changing every day or two, its much faster and easier than translating all of it.
The only time there is something necessary for translation tends to be after a maintenance when some new content, or additional upgrade to the thing we already have are being implemented.
And seeing as Roentgen got reliable info on the last two, I dont doubt he will give us the heads up when something big happens
