Amount of Studies on Desktop vs Mobile

When I am on my laptop, I am pretty consistently shown new surveys.

On my phone, it is exceedingly rare for me to see new surveys.

Would it be a matter of being logged in on both platforms at once? I don't have this issue with Cloud Research, though at least there on mobile it is made clear that I need to switch to desktop for certain surveys.

Just curious if there are any dual users who are on Mobile more or solely on mobile who get consistent invites.
