See directions and screenshots at the below link, including what to do if your OS is outdated.
How to update your eBay app
Requires Android 10 or better
Requires iOS 17 or better, but there are directions for iOS 16 users to download an older version of the app
If you cannot update to a compatible OS then you'll have to access eBay from a web browser on your device and you'll probably want to delete the app so links open in your browser instead of the app.
With an old iPhone 6s you won't be able to update past iOS 15 which means you'll have to use the phone's browser.
