Can’t pick up shifts? (flex)

Today is my first day as a flex locker+ associate. I get multiple notifications of shifts but when I go to look at the shifts, there are none available.

I asked my he and they seemed just as confused.

Is this normal? Is it because I haven’t actually worked my first shift yet? Is it hard to pick up shifts as a flex and/or locker+ associate?

i know I could just ask later on when I go but I can’t wait.
