I purchased the soft top kettle in April 2020. It has now developed cracks at the base of the interior water windows. Is it still safe to use?

I bought this kettle because I was attracted by the design. Kettles can be boring, but this one sits proudly in its cradle, exhibiting luxury. When reaching the boil it gives off a short ding, in case you're otherwise distracted.

I bought this kettle about 6 months ago and absolutely love the look. A bit heavier than the average kettle, but that's not my main issue. I can never tell how much water is in the kettle without lifting it up to the light or window. My kitchen can be quite dark and in this day and age I thought that that light up feature or a more obvious indicator would have been the norm especially considering that it is an expensive item to have. I also have the large Sage Toaster which is perfect for my sourdough slices.
