Мое приложение - это отдельное приложение на Экспо, использующее expo eject.
. Моя проблема в том, что при перемещении экрана я могу видеть заставку в течение очень короткого времени, и экран отображается.В чем причина и как я могу отключить заставку?
Я хочу избавиться от этой проблемы, поскольку она довольно навязчива в пользовательском интерфейсе.
