Is XRP actually used?

I've been hearing a lot about XRP, but I'm still not sure if it's actually being used in real-world transactions. Can you provide some insight into how widely adopted XRP is, and what types of businesses or industries are currently utilizing it? I'm particularly interested in hearing about any notable partnerships or integrations that XRP has secured, as well as any recent trends or statistics that indicate its growing popularity and usage. Additionally, I'd like to know if there are any limitations or challenges that XRP faces in terms of its adoption and usage.
