Now when I hit reply on an email and it opens up a new reply page, the page automatically jumps down to the bottom of the original email, and not staying atop the whole thing to reply. When I scroll back up to the reply section (like any email is supposed to do), it will automatically jump back down again. Even if I stay typing quickly, the slightest split second pause in typing and it jumps back down. Makes it impossible to reply. Fix this issue. App is updated etc.

A little sluggish and a little non-intuitive when deleting emails. Nonetheless, it has almost all the capabilities as the desktop browser equivalent. My issues are with the notification service. I will sometimes get push notifications for new emails, even after I open and read the emails. Doesn't matter if I rad them via the app or desktop site. Also, I am not a fan of the way emails are viewed. There is no zoom capability and the way it goes to the next email after deleting an email. Otherwise, this is still a great alternative to most email providers.

Thanks for your feedback and the bug report. We've just fixed a notification issue, please check whether this improves with the next version. Zooming is possible with a double-tap.

Has potential. Love the idea. However, I have not been able to receive alarms/notifications which means the calendar is not so useful. Even with battery optimization turned off, on android 9, it does not work. I also downloaded the desktop client and never received notifications. Seems to be some issues with setting alarms as well. I understand that in the past there was the ability to import contacts. I believe that said that it was a bug and they were repairing the problem. I have been checking for weeks and there has been no change. Many people would love to get away from google, Hotmail/outlook, and others, but are not going to want to enter contacts manually. I was considering the premium service, but there needs to be a response to something as critical as a problem importing contacts. Therefore, without a calendar with alarm/notifications, and no simple way to import contacts, I have uninstalled the desktop and Mobile app. You have great ideas, it just needs work. Good Luck.

Thanks Jonathan, notifications should work on your device. Could you please send details to hello@tutao.de so that we can check this? The contact import has only be broken for a few days now, and it will be back this week. Sorry that the bug occured during your time of testing Tutanota. Hope to see you again in the future.
