If you have a feature request or want to report a problem with an application, please first make sure you are running the latest version of both the app and iOS/macOS.
If that doesn’t resolve your issue, please contact me using the Send Feedback button you’ll find in the app itself. This will attach some additional information to your message, so I won’t have to ask you for it later.
If that is not possible, you can email me. If you do, please remember to tell me what device you’re using, and what app you’re talking about :)
Please describe the issue in as much detail as possible.
