I've been a user and paid subscriber to Dropbox for about a decade. I use Drobox for sharing my files across multiple devices and occasionally for sharing files with other people who don't always have Dropbox accounts. I don't work as part of an organisation so I don't use any of the team or business related features. I often recommend people use Dropbox over other cloud storage as I've always been impressed with Dropbox.
I've just started seeing the normal green background tick replaced with a white background tick on multiple files and folders. According to the help pages these white background ticks can only appear on folders yet I have them on multiple files.
The help page says this green tick with a white background and green circle 'Contains files that are both available offline and online-only. A white circle with a green outline and a green checkmark can only appear on a folder. It means the folder contains a mix of files and folders that are ”available offline” and “online-only”.'
Looking at the files it looks like some of these are files I've previously shared with other people but that doesn’t match the description here. My recolection is the shared folders had a different icon but that seems to have changed.
What would be nice would be for a company to be consistent with their icons rather that occasionally going for a total redesign just because someone has said it's fashionable to have a new look. If you have to have a new look please, at least, keep the basic symbolism consistent with the past for the sake of your long term loyal customers. When you do release an update please also release an update of the help files as the statement that 'A white circle with a green outline and a green checkmark can only appear on a folder' is not true as I have it all over my files.
