I'm finding it = I am in the middle of ... and it is ....
To use = tsukau but you already knew that.
I'm finding it easy to use = I am using it and it is easy.
I find it easy to use seems correct in grammar but it isn't natural.
I found it easy to use = I used it and it was easy.
Does this help?
Thank you so much ☀️
