What is the problem with Ethereum Lido?

I've been hearing some buzz around Ethereum Lido, but I'm not quite sure what the fuss is all about. Could you please elaborate on what are the major issues surrounding Ethereum Lido? I'm particularly interested in understanding its technical challenges, if any, as well as any potential security risks it might pose to investors. Additionally, I'd like to know if there are any scalability concerns or performance bottlenecks that have been reported with this platform. Finally, it would be helpful to get your opinion on whether these issues are being actively addressed by the development team and what measures are being taken to mitigate them.
