Why Does This Warning Appear?
WhatsApp may block or limit logins from unsupported builds. The message aligns with Help Center guidance that unofficial apps are not supported.
Does the Warning Mean Your Account Is Banned?
Not always. Some users see warnings before a temporary restriction; others can still send messages briefly. Compare symptoms with why a GB WhatsApp account may be banned.
What Should You Do Next?
Read the Full Warning Message
Check for timers, support links, or instructions to install official WhatsApp.
Check Whether Your Account Is Restricted
Try official WhatsApp on the same number in parallel only if instructions allow. Do not share verification codes with third parties.
Consider Switching to Official WhatsApp
If the number is important, migrating may be safer than hunting another MOD. See switch from GB WhatsApp to official WhatsApp.
How to Prepare Your Chat History Before Switching
Export or back up using options your current build supports. Cloud backups from modified apps may not restore into official WhatsApp.
What Not to Do When the Warning Appears
Do not install random “anti-ban” APKs, do not bypass warnings with unknown patches, and do not repeatedly request SMS codes. For code issues unrelated to this banner, see verification code not received.
