thinking about it yourself.
others suggest to clear the cache for your Google Play, or disable play protected, or remove the original game installation. whatever you do, your phone prevents installation. there's nothing wrong with the mod apk itself.
if the mod sometimes works and sometimes doesn't work, can you give more information? when did you activate the mod (before logging in, after inside the game, when?). did you activate, then deactivate, then activate the mod several times? my testing always succeeds by waiting until the main login button appears then activating the mod then clicking the "enter the game" button. it seems like the mod always works. give me more info and maybe I can check it. thank you
Always stuck in loading and will force close if you go to settings and give permission first, then that will be resolved only after that the mod does not work as it should and when entering again will be stuck in loading aga in and force close
