Mainz - Permanent residence timeline

Greetings,

I've searched in the sub, but couldn't find info.

If anyone in Mainz has recently got their permanent residency with a Blue Card, I would like to ask the following:

-How long after the online application did they get back to you?

-Did they request the "Leben in Deutschland" test results even though you had the "Einbürgerungstest"?

-How much time passed between your online application and actually receiving your permanent residency?

Thanks!
