I heard something different about immunity.
As in there ain’t none.
If it follows the pattern of other Corona virus immunity, you'll build antibodies against it while infected. If you "recover", those antibodies will afford some protection for a year or so against the virus that you survived. It won't be a life long immunity. You're at risk again when it fades.

If there were no immunity, nobody would recover in the first place. They’d just die or become a seething pile of virons. Immunity is a product of the body defending itself from the virus once it gets infected.
Cross-strain immunity is a different matter. It depends on how and in what ways one strain differs form another. Immunity then becomes a spectrum from “none” to “complete”.
The reinfection stories, while there are enough of them to not dismiss it out of hand, are likely the result of incomplete recovery (relapse) or exposure to a different strain. Likely. Highly likely, even. But not certain, because this virus as so many weapons in its arsenal that little would surprise me at this point.
