Very happy to see that now the Android Proton Mail app supports conversation (even if the "conversation" concept is still broken in Proton Mail in general).
That being said the update was a giant mess. It completely logged me out and I missed timely notifications for emails I was waiting for. Then there was multiple Notification called "Emails" in the Android Notification panel thus reverting my notification sound to the default one... Had to uninstall/reinstall to fix
