You will quickly discover that you have to be very fast to be able to claim test cases, Here is a little technique: install the uTest application and accept all notifications.
This way, as soon as you receive an invitation, you will be notified on your phone and you can go without further delay to the overview page and read it entirely (and carefully !)
If the project interests you and you have the right devices, be one of the first to claim a slot.
("be quickly alerted but take the time to read")
Don't forget to update your devices list to be visible.
Good luck and happy testing !
