In the previous post, we notified that the current version of Serialna (～Ver2.0.2) is not available on iOS9.
That status is not changed on the latest update, iOS9.0.2, either.
We continue to ask you not to update iOS.
We plan to release a version of Serialna that will address the issue with iOS9 in the next few days
and ask for your patience for just a while longer.
We apologize for the inconvenience.
