Victoria Bampton (aka the Lightroom Queen) has created a free ebook describing a travel workflow for Lightroom Classic users. You can take photos with your phone or regular camera. These get synched with Lightroom (cloud) while you're away. When you return home, the photos synch back to your Lightroom Classic catalog. I highly recommend this succinct workflow.
To get your copy, visit the Lightroom Queen website and click the Downloads link. Scroll down to the Lightroom Classic & Mobile - Travel Workflow e-book. You do need to register for a free account to download the guide.
Also, you can suggest and vote on recommended improvements to the new Masking feature. Several user suggestions have already been marked Planned by Adobe reps.
