I am using Google Photos to share family albums and I am trying to determine if I can replace Google Photos with Proton Drive (I am a Proton Duo user). One very useful feature for the users I am sharing the albums with is the ability to add comments. In fact, this would be a show-stopper if it is not possible. The reason is that some of the photos are pretty old (scans of standard prints) and lack details. Being able to add comments is a great and simple way of sharing and improving the information we have about some of these photos.
