Microsoft Store... Not always the language pack version is the same as the coming build, only sometimes.
The language experience packages from the store are showing a new build number, not always correctly enough to predict the next IP build number.
I don't understand what you wrote but I know what you mean. The language experience package version is 18927 . Maybe you are not on the Fast ring (I think you need to be insider on Fast ring) to receive this language experience package update
