No trail lessons yet (Physics Tutor)

I joined Preply recently to teach Physics and made my profile visible 2 weeks ago. I have a master's degree in Physics and I had uploaded it to get it verified by Preply, which they did. Having read multiple older posts here, I had listed my hourly rate to be 15$ because as the older posts said, I should not undervalue myself or I risk being seen as someone who isn't genuinely confident in themselves.

But now I am sitting here with not a single trail lesson in 2 weeks. I lowered my rate today. Is there something else I can do to make myself visible to students?
