I'm in the same shoes as you. This has happened 3 times in my case and I have 100% profile completeness, along with over 5 tests taken. I've asked questions here on the forum hoping someone would be able to shed some light and review my profile in case there's something I'm missing.
Have you checked your profile completeness? Also, have you looked through the forum for guides on setting up your profile, writing an overview and all that? I referred to those while trying to figure it out, perhaps this step can make a difference in your situation.
Lemme know how it goes.
