That's unfortunate that they aren't giving you more tasking, especially if you're asking for more. But, without knowing too many details, it probably is just the normal ebb and flow.
My experience is that it can take several months to a year before I get really fully spun up on a new job. A lot of more senior people generally feel that it will take longer to hand off a task to someone new than to do it themselves. So it takes time for them to know and get comfortable with your skills and abilities.
