I've been trying to get answers from Proton for literal months concerning critical functionality issues with their mobile Android client. Messages are often truncated / missing data; clearly, there's a disconnect between the cached version of the message and the message the user sees. Unfortunately, every attempt to resolve this with support is met with boilerplate "try our beta app" at best, ghosting at worst.
I have supported Proton as a paid user since 2018. It would be nice to think that they value their early adopters, but... honestly... their actions suggest otherwise.
Edit: Proton acknowledges the issue, offers no timeline for a fix:
Please be informed that the issue has been reported and our developers are aware, they are look for fixing it in one of the future updates of the app. Unfortunately, we cannot provide an ETA on when the permanent fix will be available.
In fairness, that might actually work if he were a corporation. "Lol our bad we declare bankruptcy and 'restructure' after fucking over our creditors."
