Tiny Calendar Resets to Home Page

Ive had Tiny Calendar for some time and recently it now at iOS 10.2 will reset to the homepage after launching. I deleted the app and reinstalled it only now to have it reset during the "sync for first time" message.

There is NO "Contact Us" for the Developer appxy at appxy.com to see if there is a fix.

Anyone have this experience and fixed it?
