Student unable to use Text Box feature

My student is not able to use the Text box feature on Kami to type on her assignments. I’ve tried to trouble shoot with her, but don’t know why it’s not working. Her ELD teacher also tried helping, but couldn’t figure it out. Suggesions?

I never had that promblem… Try having the student refreshing Kami
Or even maybe Kami app needs to upload to her device again.

I will search it and tell you
