Hi.. Really help someone can advise on this as I am getting nowhere with seller support.

All our listings are SFP but are not displaying the prime badge and are currently showing 3 day delivery.

Was originally told by seller support to disable SSA which we did, this did make our listings show next day delivery but still no prime badge, was then advised to enable SSA which has them all now showing 3 day delivery again

Orders are still showing to be dispatched same day as they are still prime orders but just not showing the prime badge or next day delivery

all shipping settings are correct and Prime enabled

Seller support originally said maybe our carrier (Royal Mail) was not meeting delivery expectations, however I then informed them that we have..

100% on time delivery

100% on time dispatch

100% of delivery purchased through Amazon buy shipping with a linked Royal mail business account so they agreed this was not the case.

Also 0% order cancellation and account is healthy

SSA activated with Royal mail tracked 24 as preferred service

none of my inventory display "FREE Shipping for Prime members" or "Prime FREE Delivery" messaging rather than the Prime badge itself.. they all show 3 day delivery

And to make things worse all the links Amazon are sending me to reply are opening in french, some serious glitches here, is this issue happening to any other sellers.?

Thanks for any help.
