Spontaneously crashes after a while – GoodNotes 4 Review

I really like this app. I use it for note taking my masters level courses...but what I do not love is the spontaneous closing it does when it’s been open for a while. It typically does this when I am moving to a new/fresh page of notes. It will spontaneously close, often times erasing the last few things I wrote. This is a little infuriating when this happens, and I have no idea why it does. Otherwise, this app accomplishes everything I need. A fix for this bug would be great!
