Hi @raymc16 & @mattprops ,

The eBay app won't work on iphone 6 s or iphone 7 as they have older operating systems that are no longer compatible with eBay.  It should work ok with going through the browser and not the app.  If it is not working with the browser what could be happening is if you have the app on the phone is it could be defaulting to the app automatically.  Suggestions here would be to delete the app and then log into eBay through the browser or alternatively if you have access to a desktop/laptop log into your account on that.

Thank you,

Kat
