@Tutanota my biggest issue right now is notifications on mobile. Opening the notification doesn't take my to the email, and I have to dig through my inboxes to find where it was sent! Also wish it didn't sync on app open, feels unresponsive. Would be nice if it synced in the background before I opened and it'd be responsive as soon as I open the app.
@shipp Thanks for your feedback, we'll see what we can do! It syncs after logging in as your inbox rules are encrypted and only applied after you decrypted these with your password. This way we make sure that we know nothing about your emails/content/rules.
