All the tests that I’ve done past august 18 are gone and the entire site has no tests and is completely empty I’m not sure if the site is down or its my end can i get answers is there something i can do here first time encountering this.

A week ago, I took a screener asking if I’d like to participate in a 3-phase study over the span of a week. I already finished the first phase, but I haven't seen any screener or received an invitation for the 2nd and 3rd phases. ​Is this common behavior? I would really hate to wake up one day and see a 1-star rating on the first phase because I didn't go through with the 2nd and 3rd ones.

​Is it possible that I missed the screener? Can researchers target specific users to make sure only they get the screener?
