How to change keyboard back to simultaneous language after Samsung s7 update?

[AC Question]

I'm having the same problem. I had English, Persian. I would change the language on the spacebar, depending in which language I would type. After the update, it all went away. I added the languages again, but the keyboard is stuck on English. No autocorrect on the other languages and no keyboard to use special cartographic items. How can I fix this problem?

Custom keyboard might help. SwiftKey is seamless in a number of languages...
