Thanks, Judy, that fixes the listing warnings, but why do we have to make that selection for each and every Lot?
In Profiles, there's a setting for this (I just now set all four active Profiles), but as far as I can tell, it doesn't kick in automatically. However, I'm doing relists, so maybe it will kick in for newly-created Lots -- ??
P.S. Isn't it just so annoyingly typical of Help files in general and eBay in particular that when you enter "maximum dispatch time" in the Help Search box, you get, "Sorry, we didn't find anything."
