I’ve received an email with new assignments. Then I open the app and I cannot find not even fine one of the new assignments. Can anyone please let me know if they have the same issues? Are jobs taken that quickly?

Jobs go very quickly! Make sure to update your notifications so that you are able to respond quickly.!

I'm very new to all of this can someone please explain what to do?

This same thing just happened to me, I just got the email and as soon as I could log in they were gone. I live in a very rural area and I have never seen them gone this quickly, but I'm sure it happens!
