Auto correct issues with Icelandic

Hello. After updating to iOS 11, auto correct for Icelandic is much worse than before and borders on being completely unusable.

It replaces very common Icelandic words with other words. One of the more common ones is the word “koma” (come), which is always “corrected” to other words.

This is happening on both an updated iPhone 6 Plus and an iPhone X (and I’ve heard the same from many users).

Is there any way to flag this issue with Apple?
