Has anyone got any experience of upgrading back to the Avios+ card after previously downgrading to the basic Avios card? I downgraded many months ago after achieving the voucher, and am ready again to try for a new voucher (the card year seems to have reset on downgrade), but the 'change card' feature in the app only shows me two other unrelated Barclaycards.

Is there something I could be doing to try trigger the Avios+ to appear there, or will it just take some time, or may never appear as an option?
