Pre-registration is now available for this (which will earn everyone who’s done so [& who’s playing the beta version?] in-game rewards) via the game’s website & the Google Play Store. There’s not yet a date available for the UK launch beyond “2023” - apparently extreme caution is the approach on this one.
I am still mourning the loss of Wizards Unite & am not-infrequently irked by various aspects of Hogwarts Mystery (but enjoy it enough to keep playing) so - given I’ve only my phone, watch & a rather antique & limited kindle when it comes to tech (I’ve not a TV, no) - I’m hoping this will bring me a wee bit more Potter-y joy.
