I have that problem too
Shash łóóʼ yį́yą́. Is what I keep putting, but it still keeps counting it wrong.
Still counts it wrong.
I have the same issue...
By using an european Keyboard and to be confimed right I write it like this " Shash tóó' yiyá' "
At least it worked for me - always.
Shash tóó' yíyá' worked
In which keyboard can i get that line above the y?
