If this is a Proton grievance panel, I really wish they'd optimize their web app, at least with Firefox. If I leave the Protonmail tab open, the amount of CPU and RAM usage for Firefox just spikes up like crazy, and it shoots back down once I close that tab.
I can get around this with the ProtonMail Bridge and using Mutt, which works fine and makes me feel cool, but the web app is considerably more convenient.
Both their web app and their android app are extraordinarily sluggish, unfortunately. And I currently am forced to use the web app in a PWA on my phone because the Android app has a current bug where the contents of emails won't load. In other words it's 100% useless, and I uninstalled. By the PWA is agonizing to use, so I've been missing emails lately. For a service to keep getting worse over the years when I want to like it is difficult to swallow, but every day I'm a little closer to canceling my subscription.
When I would type and send an email too fast, it would only send the first half or so. I would have to type out the email, wait about 30 seconds, then send it. Presumably it had to fully save some draft before sending it, but it came off as extremely amateurish. Not to mention that it just utterly killed my battery life.
The iOS app is fine, and since I'm on iPhone again I'm still on Proton, but I haven't completely lost the bitter taste in my mouth over the Android version.
I don't have an Android phone anymore, and to be potentially fair to Proton, my last Android phone was an utter piece of shit (Pixel 7 Pro). I know people who had the Pixel 7 Pro and they didn't seem to hate it, so it's possible that it had some hardware issues, but it certainly didn't seem like hardware issues. I hated that thing so much that it completely turned me off of Android for the foreseeable future, since this was not a cheap phone, and it was Google's flagship phone: if they couldn't get a good experience on the flagship product, I didn't see why the experience would be much better on anything else.
Anyway, it's possible that the Proton app didn't suck as generally on Android as it did for me, it could have been the phone's fault, but it did leave a very bad taste in my mouth. As stated, the iOS version of the Proton app is totally fine, I haven't had any issues with it other than I don't really like the theme, but that's hardly worth complaining about.
With the previous android app, not the one they just launched last month, i had a similar issue (it would take ages to load an email), clearing the cache in the settings had solved it though.
I feel like this is a somewhat recent change, so I don't know what happened on my computer or within Protonmail; I have an Intel Macbook Pro, and it really seems to slow everything down. Maybe I screwed up a setting but as I said everything else seems to work fine and when I use the Protonmail Bridge it works fine.
Yes, could potentially be related to a different CPU architecture, but could also be something else eg RAM capacity (I have 64GB) or Proton Mail settings (do you have offline enabled? I don't).
I have 64gb of RAM as well. I don't think I have offline enabled. My CPU is an i9.
I'm happy enough with my Mutt solution, and the iOS app is generally ok, and I do like the service overall, so while I complain it's not out of hatred. I just want the service to get better.
Is there some trick to get Mutt's "e" command to work ? My editor (emacs) says the message writes back to the server okay, but then my edits do not "take" on the server.
