I have been using language toolbar and 4 different keyboard languages (English, Spanish, Russian and Latvian) without any issues for about half a year in Windows 10.
This morning I suddenly realized that Spanish language has disappeared from the language toolbar. But it still was showed as "installed" in the language preferences!
I experimented with different kind of options, set the "old type of language bar" and from there I could switch to Spanish.
Then I realized language switching hot keys do not work, even if they appear to be set, just do not work.
In the meantime, now Latvian language disappeared from the language bar, and the "old type of language bar" also disappered.
I am very confused why languages keep disappearing from the language bar!
