Is one of the changes to prevent modifying the answer after tapping info for a submitted answer? The keyboard no longer pops ups after submit, tapping info, tapping input to change the submission text.
Also, the delete sometimes erases the whole answer regardless of correctness after a submission with user settings set to make the delete key erase one character. This behavior is nondeterministic, mostly works but sometimes doesn’t.
Not big things, reporting just in case you want these on a low priority list somewhere.
