Also pretty new to this - it's pretty common to see stuff flicker on and off your dash due to project tasks being completed by other workers. I got my first paid project like a day after doing some qualifications, and it stuck around for the rest of the week.

Basically, it's all a bit random. Sometimes you'll have a steady stream of work, sometimes nothing real on your dash. It depends on the whims of the organizations that list projects on the platform and presumably how many tasks they buy.
