Slow uploads and downloads, if they even manage to finish in the first place. Background operations are unreliable. The photo backup is essentially broken, I spent a week trying to upload my photos, but gave up eventually. No way to periodically automatically backup an Android folder in the background. No way to tell how much storage each folder is using. The "Computers" tab doesn't show any of my computers running the Proton Drive desktop clients. It is also (somehow) still missing file search

‘Computers’ displays any devices you’re backing up folders from using our Windows app only. On Android, the backup process works most efficiently during daytime use. For help with the other issues, use the in-app ‘Report a bug’ option. Edit: Search is on our long-term roadmap.

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.

Thank you for your honest feedback - we'll share it with the team. Sheets were just recently introduced, and we’re working on making them available on mobile as well.

Although I do like the privacy that Proton Drive provides, the Android app is garbage. It is so S L O W. It takes forever for files to load and when it does, it takes up a lot of space on your phone (so much for cloud storage). Sometimes, if you're really unlucky, it might crash while trying to load your files. Honestly, you're just better of using Proton Drive through a web browser. I really hope all of this gets fixed soon.

Hey Matt. Sorry to hear about your experience with the app. Could you submit a bug report via the "Report a bug" feature in the app so we can help you troubleshoot?
