I recently changed my number and deleted my WhatsApp app off of my phone. However, after reinstalling the app and changing my number, I was informed that my WhatsApp back up had been deleted off of Google drive. This is very important to me as this contains my work information as I am a registered nurse, my images, videos, voice notes, and other data that has also been deleted from my phone. Please help with this matter as this back up is usually not emptied into the trash folder
