Very disappointed with the update

After the update, it becomes really laggy when I type using the extended feature and then exits after. As someone who needs to study all the time, this is the worst. I use this app in my everyday life, meaning that all the files i need are on this app and now you’re telling me that I need to always open the app to edit every letter i type?!?!? VERY DISAPPOINTED!! IT WILL SUDDENLY CRASH FIX THIS PLEASE I HAVE AN EXAM TOMORROW GREAT WASTE OF TIME REALLY!!

Hello, we sincerely apologize for the unpleasant experience you’ve had. May we ask if this issue still occurs when you use the product?
