I am a photographer and I need to travel as light as possible. This means I usually have to rely heavy on my iPad Pro. Unfortunately LR mobile lacks in a critical point

The ability to tag multiple images in LR mobile and then adding keywords to all that photos at once would be highly appreciated. I am not even asking for hierarchical keywords. I was asking for this feature 3 years ago and i was eagerly waiting for it with every new software release. I am incredible disappointed. Organizing photos and adding keywords is one of the original core functions concerning Lightroom. There are many photographers out there who miss this feature (adding keywords to MULTIPLE photos at once).
