If you look at the page for this app in the App Store, you can see that they have not updated their app for 7 months. Meanwhile an entire new iOS has been released. So it's not all that surprising to me that you'd be having issues.
Here is a support article for contacting an app developer
How to contact an app developer - Apple Support
On their page in the App Store, scroll down until you see a link for 'Developer Website', when you navigate there, at the bottom of their website there is a contact link. It will open an email and you can ask them when they plan to update their app.
