How to Intersect Mask with Lightroom (cloud-based)

[BiJeiTi_Ph]

The new masking options was interesting. But I have a question?

Is it possible to use the command "Intersect Mask with" also in Lightroom cloud based?

The command was very powerfull in Lightroom classic but seems not present in Lr cloud.

Any suggestion?

If not present I suggest to introduce it as soon as possible.

Lightroom Desktop did not have a legacy workflow using Range Mask as did Classic and Camera Raw. 

To accomplish an Intersect on the Desktop/Mobile clients use Subtract+Invert.

I found this choice questionable. This is a new instrumet for all the three software Lr - Lrc - Cr but we have some difference from the launch date.

I suggest leveling the potential of the three software.

Moreover Lr and Lrc can work in the same image when a image is in a synced folder, so please evaluate to have same workflow.

I agree with the other comments here. Intersect was the default (and only) option in Lightroom Classic since range masks were introduced. I do not understand why the improved masking functionality would be added without the Intersect option. As you stated, it can be accomplished with Subtract+Invert, but why not just add Intersect directly as an option rather than making users go through the mental gymnastics of thinking about inverting the mask?

I second this. Intersect is probably the boolean operation I use most in Lightroom Desktop, and I was surprised to not be able to find it in Lightroom Mobile on the iPhone.
