It's a great product, and I'm quite happy with its main "share file" feature.

Unfortunately, the file management is not perfect at the moment, but it's a minor flaw that doesn't affect the main features I use.
Incidentally, I've heard back from the officials that in 2023, this product will get an even more powerful file management feature!

Apart from the product itself, I am quite satisfied with the speed of the official reply.
I believe that this product will be the most competitive product in the market if it continues to improve.
