### 3/5 — Хорошо, но часто вылетает

*2021-06-16, version 4.20.1*

Приложение удобное, но бесит когда вдруг начинает вылетать. Ты запускаешь, а оно закрывается.

По опыту, такое случается если письма зависают в исходящих, но бывают и другие причины.

Исправить можно только через удаление и новую установку и настройку. Что крайне не удобно в разгар рабочего дня и необходимости срочных коммуникаций.

### 5/5 — Help, please!)
