Reasons of WhatsApp Business not updating:

• Error Codes: When your Google account is messed up, error codes can impact WhatsApp. If you have a lot of Google accounts, error codes can cause WhatsApp to stop updating.
• There isn't enough memory on the device: WhatsApp will not update if your smartphone does not have adequate space to install the current version.
• Your Android/iOS device is incompatible with WhatsApp: Some older Android phones do not support the latest WhatsApp version.
• Your nation does not have WhatsApp: WhatsApp's latest version may be unavailable in your country, which is why it does not automatically update from the Play Store or App Store.
• The most common and basic solution for any problem that happens on an iPhone, including the WhatsApp not updating issue, is to force restart the device.
• Uninstalling and reinstalling an app on your phone will sometimes resolve any issues with that app.
