I really like the service but I hate the app, it works so incredibly slow even after all the photos have been uploaded. It's incredibly hard to navigate the photo gallery and look back on memories when none of the photos appear to load. I really like proton as a company overall, so im hoping it works better in future

Hi! We've enhanced the photo loading time in the latest version of the app. If photos are still loading rather slowly on your end, please report this via the in-app 'Report a bug' option.

I enjoy using Proton's email service but this one is undercooked as it is right now. I have tried multiple ways of opening a document within Proton Drive and it just won't allow me to view/edit it at all. Opening it elsewhere, like in Google Drive or Dropbox, works fine, so I don't know what the issue is. Hopefully it gets addressed soon but I'm definitely dropping my subscription if I can't actually open/view/edit my files while away from my desktop. Edit: For the developer, it was a docx file

Thank you for your feedback! Could you let us know which file type you've attempted this with? EDIT: Docx files are not yet previewable directly in the app. A possible workaround at this time is converting them to Docs (our proprietary format) on the Proton Drive web client first: proton.me/support/drive-import-export-docs

Extremely buggy, but does the job…mostly. Often randomly boots me out of edit mode, there's no option for find & replace, no actual dark mode (document itself is blinding in the dark), font selection options immediately close after opening so you can't actually change the font, no viewing option for print layout, extremely limited color and highlight options…those are the big issues I have, and I'm sure I could go on. Still, it helps me get my thoughts down, and it's not jammed with ads and AI.
