Troubleshooting sending messages on Android

We’re aware of some rare issues with sending messages in the Proton Mail Android app, and we’re actively working to fix them as soon as possible. 

Meanwhile, you can use the Proton Mail web app (mail.proton.me(new window)) from your Android phone and add it to your home screen for quicker access.

How to tell if you’re affected

We’ve identified some rare scenarios where sending messages doesn’t work, resulting in one or more of the following issues:

• Messages get sent with empty or partially cut-off content.
• The Proton Mail app gets stuck on “Sending message”.
• The Proton Mail app displays an error message saying, “Message send failure”.

You can add the Proton Mail web app to your Android home screen to continue sending messages while we resolve these issues.
