Its a shame that this is so unintuitive... The features seem useful and rewarding, but the overcomplicated process of linking accounts is insane. All I wanted was to use the new Check-In feature, linked HoYolab to PSN (I play on a playstation) i still needed to link to google... Which cannot be done on exsisting mihoyo accounts... And is explained no where except in the frustrated posts of forum users who also are struggling. Genshin Impact is awesome... The app is not.
