App no longer works – Yandex Mail - Email App Review

This app no longer works on my phone. After months of flawless use, one day last week it just stopped working I am no longer able to log in. I’ve uninstalled and reinstalled several times to know avail. The Apple store app support appears in Russian which is no good to me.
