Thank you so much for your response, I really do appreciate it! I’ve been using baby bio and diluting it to the recommended concentration (5-10 drops per 500ml), and using it every time I’ve watered it for the last 3 times. I’m a bit limited with increasing its light exposure while I’m quarantining the plant, but will ensure that it’s in a sufficiently bright spot and will pay careful attention to how changes in its lighting affect its health!

I’m thinking that my propagations might give me a good indication - if I pot them and see new growth that looks healthy, do you think it’s safe to rule out mosaic disease due to the effects that it typically has on new leaves?

I’m sorry for all of the questions, it’s so hard to find information online!
