I don’t know what it is about this app specifically that the developers just can’t get to work properly, but this app has been a massive letdown since I started using it over a year ago. At the time, I figured it was just needing a patch, which I had come to trust and expect, given my excellent experience with the rest of the Proton suite, but this app specifically performs absolutely abysmally even now, using the latest version, and seemingly hasn’t made any significant progress in terms of performance since I started using it. Everything from just loading into it to tapping on the files tab to simply opening a file I’ve already downloaded (!!!) is sluggish, messy process, and I can’t recommend using this app on mobile to anyone. The desktop version on both Mac and Windows works fine, and like I said, the rest of Proton’s apps on iOS work great, but this app on this platform specifically is a performance nightmare. I’m not using a particularly old device or iOS version either. I’m running the latest version of the app on iOS 18.5 on my iPhone 13 Pro Max. Please do better Proton, I thoroughly enjoy using these apps, and I hope this app can be brought up to the level of quality and UX that I’ve come to expect from the rest of the apps.
Thank you for sharing such detailed feedback. We’re truly sorry to hear about your experience with the app’s performance on iOS -- this is an aspect we're constantly working on improving. If you haven't done so thus far, please send the details about the behavior you're experiencing and include your app logs in your report via the in-app 'Report a problem' option so we can investigate further and work toward improvements.
