I've looked at orders delivery estimates from similar times last friday and it looks as though it happened then too so im hoping its just a temporary friday glitch, hopefully one day the tech team will actually take note of all our complaints regarding it not working as designed.
I have a pattern on saturday mornings (up until around 11am) where ebay estimate deliveries between Monday and Tuesday, then it flips to Wednesday/Thursday after 11am, almost like clockwork week in week out (i dont send anything on weekends).
but that will be it "working as designed" according to ebay.
