P:(Masking) Save a Transparency using Masking tools

[Rad Drew]

I do a lot of product photography using the iPhone 13 Pro Max running iOS 15.1.1 and Lightroom for Mobile version 7.0.2 176DFF/67.

I use the "Select Subject" feature in the Masking Tool and it does an excellent job selecting the subject, but I'd like the ability to save it with a transparent background. 

Thanks for considering this suggestion.

Do I understand it correctly that you want the color of the overlay to be transparent (not the default red color?).
Have you tried to tap on the three dot menu button in the upper right corner?
There you can try out the different Mask overlay modes.
Hope it helps.

Thanks,
Ignacio
