kat@ebay Thank you for you reply.

But why wasn’t this implemented before the delivery change, ie last Monday?

It’s not as if it’s been a big secret. 
This affects businesses EDD and Late Delivery Rate which in turn affects TRS and those benefits.

Why are ebay always late to the party?

Its infuriating.

Is now a good time to remind the shipping team there a Bank Holiday Monday in just over 3 weeks?

Apologies for sarcasm, but there seems to be very little consideration for business sellers recently.
