Fix crash in Mail on iOS 9
We are aware of an issue in which the Mail app will crash in some cases when starting to compose a new message or reply, when PadKeys is the selected keyboard. Unfortunately this is due to a bug in Mail itself. We are trying to work around it, which we believe should be possible since not all third-party keyboards are crashing. When / if we find a solution we'll release a new version to the App Store right away.
For now unfortunately the only solution is to select another keyboard before entering Mail, and then switch to PadKeys once the message has opened. We apologize for this.
This is fixed in version 1.3.1 out now. Please report a new issue if you are still experiencing any similar problems.

Update: We have found a workaround and will be making a beta version available with that fix. If you'd like to try it out, please send an email to firstname.lastname@example.org with your Apple ID email and we will send it out to you.
If it works OK in beta testing we will release to the App Store as soon as possible thereafter. Thanks for your patience.
