Ratings and reviews

warning to others, this app is completely unreliable for work. I desperately needed to move a file from my PC to my phone today, I moved the file into the unintuitive my files folder that proton drive creates on your system, and nothing happens! copy, drag, nothing happens. I see some other files I added a while ago, no error, no feedback of any kind just doesn't work. I am reduced to transferring something on a flash drive just to get it done. I hate this sad excuse for a backup app.

Uploads are extremely unreliable, and basic features are lacking. I've consistently had a better experience using the web version than the app. No file search. No ability to have a folder watched for changes and automatically synchronize it's contents, no progress bar to see if uploads succeeded, folder uploads miss ~30% of files in the folder... All these issues have actually caused me data loss because files I uploaded seemingly without error ended up missing, which made me loose my backups.

I really wanted to love this, but as a mobile app, it's not quite there yet. you can't edit original files on the app, just view them. and actually, you can't preview most of the files, either. the only file types I've been able to load are pdf and txt. docx or odt are unable to be seen. docx/ excel files can be opened on desktop in docs/ sheets, which creates a new copied file that can then be viewed on mobile, but sheets can't be edited. it feels impossible to do this for each individual file.
