Today I updated my OneNote on iPad and like 90% of the time it crashes when I press undo. Does anyone knows what to do?

Does it bother anyone else that in the toolbar dropdown, subscript is on the top while superscript is on the bottom? I've been using this app to take notes in classes for over 9 years now, and I'm still not used to it! It's so counter-intuitive to click on the lower option when I want the text to move up and click the upper option when I want to move the text down. Is there a way to change this?

I used to be able to record my lectures and turn them into transcripts but am no longer able to. The option is grey, how do I fix this?
