I Cannot Log In to Free Fire on Vivo V60 Due to Error 21

Dear Garena Support Team, I am unable to log in to my friend’s Free Fire account on my phone and I keep receiving the error message “Failed to retrieve account data: 2.” I have my friend’s permission to contact you regarding this account, and I have been playing on this account for a long time without issues until now. My own Free Fire account works normally on the same device, and my friend can log in to their account on their own phone without any problems. The issue only appears when I try to access their account on my device, which is a Vivo V60, and I am using mobile data when playing. I have already tried basic troubleshooting such as common fixes and general solutions, but the problem still continues. I kindly request that you investigate why this specific account cannot be accessed from my device and help me resolve the “Failed to retrieve account data: 2” error so that I can continue playing on this account. Thank you for your support.
