People who are facing problem related to update error..like ( stuck on checking for updates,a message show to update the game)
First download Australia 🇦🇺 vpn from playstore and close warzone mobile and play store open the vpn and connect to the Perth 820 vpn and open playstore then an update option will come...click to update and turn off the vpn after the update is installed then connect to any other vpn ..like I connected to shuttle vpn (Australia 1)
Their was no update error I was able to play the game
It worked for me
I hope it works for u also :]
