Listen and Type - letters not typing or disappearing

Listen and type questions. When typing the answers, letters either don’t appear (including space) or they disappear again. Doesn’t seem to happen with “Fill in the blanks”. I am using an iPhone XS

Hello, Lena,
Does this still happening. We have found and fixed similar issue with the listen and type when there is a video playing, so may be this fix also have solved your problem.

Hello, I’ve just tried it and it seems to be fine now- thank you!

Cool. Happy to hear that is working Ok.
Enjoy your learning.
