How can I re use my Whatsapp?
iPhone 6, iOS 11
If you are experiencing any difficulty with third-party apps then please contact the app developer directly --> How to contact an app developer - Apple Support
Ask the App developer to release the app for lower iOS versions also. Netflix has done it.
The title of your post asks "How can I update my 6s version?"
The info about your iPhone lists "Phone 6, iOS 11"
Do you have an iPhone 6, or do you have an iPhone 6s? We ask because there is a significant difference between these models.
If you have an iPhone 6, the highest update that it can handle is iOS 12.5.6. It cannot be updated any further.
If you have an iPhone 6s, the highest update that it can handle is iOS 15.7
Even if your iPhone is iPhone 6 with iOS 12.5.6 the WhatsApp will work --> https://faq.whatsapp.com/595164741332628/?locale=en_US
