I am looking at an available shop posting with the cart icon next to it. I have the shop in my cart but when I go to select a date to request, all the days are marked green and none white. There is also no noted deadline for the shop. I try to click on the days of the calendar, but I cannot. What do I do?
Sometimes their shops get clogged up like that. If someone flakes and the job is reposted, it requires a certain number of days' buffer before the next visit can be made, and if that is more than three days from today, then you'll see exactly what you're describing. It can also happen when they have an internal scheduling code error.
Call them first thing on Monday to point out what's happening. They can manually override the latter but not the former.
