Does it register or not? Kirby 3

I registered a Kirby 3 website. After I filled in the license key, it gets accepted, but then it still says “Register” and “Buy license”…

Does anybody know how this can be? And how to solve this?

Have you killed the session and logged in again?

Killing the session didn’t help. I removed the whole site, and installed it again.
Works!

Fine! Glad you could sort it out like this.
