### 1/5 — Sucks!

### 1/5 — Потеря встроенных покупок

*2026-02-10*

Приобрёл новый телефон. Вошёл по своему Apple ID, обновил приложение.

Потерял доступ к встроенным покупкам. Еще в 2019 купил это приложение, когда оно было платным, в 2020 купил доступ к приложению без рекламы «убрать рекламу».

После обновления встроенные покупки не восстановить. Требуют деньги за подписку.

Прошу разработчика восстановить встроенные покупки.

**Developer response:** Здравствуйте. Нам жаль за неудобства. Пожалуйста, свяжитесь с нами по адресу support@lykovstudio.io, и мы поможем решить проблему. Спасибо.
