The spell-check feature should be included in a paid subscription, just as it is with other email providers. I should not be prompted to pay extra for a basic tool that services like Gmail offer for free. It feels unnecessary and disappointing.

In addition, external spell-check tools such as Linguee or Grammarly no longer work in the background, which they normally do on my notebook. By disabling this simple functionality, you effectively force users to copy and paste important or lengthy emails into other apps, which is inefficient and frustrating.
