I've noticed a small issue with my email client for quite some time now where composing a new email will have several blank lines by default.
It's not too much of an issue to simply delete them but hey, maybe no one had pointed this out before! So I filed a bug report only to get this response... basically it's not a bug, its a feature!
Proton is rebuilding their android app from the ground up. They're not going to fix something like this in the old app. You can join the beta here. https://proton.me/support/mail-android-beta
Thank you! The stupid thing is I'm literally enrolled in the beta program through the Google Play store... apparently that's the fake beta and you have to know this link for the real beta. I can confirm this issue does not exist on the "real" beta. You just saved me a lot of time.
The Google Play beta is the beta version for the existing app (aka edge version), not the rebuilt one (which isn't released yet, except as beta)
