WhatsApp became obsolete on January 13, 2018. The users were greeted with an infamous message, which prompted users to either leave testing or download the update. However, none of them worked for any users. We also faced this issue and finally resolved the issue by downloading the version available on whatsapp.com/android.
According to Techook, WhatsApp had revealed that the third-party distribution mechanism was faulty and it caused the WhatsApp Obsolete error. Moreover, the system is not in their control. Hence, the company is not in a position to fix the problem. The Facebook-owned messaging company added that users who have encountered the error were largely Xiaomi smartphones.
Commenting on the development, Xiaomi disclosed that a few users have reported the issue with WhatsApp over social media platforms. The problem is that a beta version of WhatsApp was recently placed on the Mi App Store, which got updated automatically on the smartphones.
The WhatsApp version has been refreshed to the new version on Mi App Store. Hence, users will not face the problem again with their smartphones. We encourage users to install the latest version to avoid errors in future. The company also assured that they will be vigilant with the apps available on the Mi App Store platform.
If you still face WhatsApp Obsolete error, you need to download the version from whatsapp.com/android or update the app from Mi Store App. You will not face the problem again because Xiaomi has updated the app in the store to the latest version approved by WhatsApp.
