First thing: unistall the game because you can't downgrade the version of the app, second: go to this link Harry Potter Hogwarts Mystery Ver. 5.4.0 MOD Menu APK | No Energy, Gem & Coin Costs, Unlock Shop | - Platinmods.com - Android & iOS MODs, Mobile Games & Apps download and install the 5.5.2 version, third: start the game, at the the character creation screen log into your profile and load your save then the game will restart and ask you to upgrade. fourth: close the game, app center or play store and at this point install the 5.4.0 from platinum, then restart the game and you're finished.How you done It? When I try to get that version sends me to the 5.2.2 and my phone doesn't installs that one.
let me know if you managed to do it.
