Should I stay in current company or look for new job?

Move to new job or wait for promotion??

My current position is tech support. I am wondering if I should start pursuing IT helpdesk jobs now or wait for an internal promotion. I have worked at this current job for about 13 months. I do know that the person that was in my role before got promoted Junior Cloud Azure Administrator. What would be the better path. leaving and looking for a helpdesk role of waiting another 11 months for a promotion to a position like that? I do know they promote at about 2 years.

Current role i make about 25 an hour so leaving for a new job probably wouldn’t get me more money right now. But that experience would be good.
