Package name selection is important. If you choose the wrong package name, WhatsApp Aero will be installed from scratch and will ask you to verify the number again, so you must choose the correct package name.
To choose the correct package name, check what is written under the "Package" text in Aero Privileges > About shown step by step in the screenshot below, so you will know the package name you are currently using.
Check your own package name as shown in step 3 of the screenshot above.
⚪ If your package name is com.aero, select the com.aero package from the package selection screen.
⚪ If your package name is com.whatsapp, select the com.wa package from the package selection screen.
⚪ If your package name is com.aerolla, select the com.aerolla package from the package selection screen.
When you do everything right, you will have updated WhatsApp Aero.
