- Yes u can... but after the problem with google and more than 1 week without update, the last year, devs decide do it ingame.
- You CAN bind acc. any time to google or fb. I never saw any restriction.
- You better do it, cos they will change the name of the game to global (stupid decision) on the next update (5th march), the name brave 9 lol.
- So you need update client and dowload the new apk with the new name.
1. Always remove original apk 1st, then install the mod apk.
2. You have google play protect on. "Google Setting" -> "Security" -> "Google Play Protect" -> "Scan device for security threats". Uncheck it.
3. You have the mod apk corrupted. Download it again.
Maybe i missing something else, but at the moment, those are the common one.
