I'm just doing my postage for tomorrow and finding I can't select RM Tracked 48. Only Tracked 24 is available as the option for 48 is currently saying "Does not meet promised delivery date". I have never had this issue before and none of my postage settings have changed.. so has maybe Royal Mail informed Amazon of delays, or is this some type of error? Anyone else having the same issues not being able to select Tracked 48? Strangely normal 48 (CRL) is still available!

Cheers
